Calling A Php Function From A Form Selection List

Apr 16, 2007

I have a function that will read records from the database and populate an area of my webpage based on a value selected from a list box. 

I have got it to work fine if the user hits a submit button but I was wondering if it possible to perform the function dynamically each time the user changes the value in the list box.

Aug 31, 2005

I have developed a database in mysql and php for contact management. I have programed in several older languages but am new to both mysql and php. I need to display information in a form but want to select the record from a drop down list either by typing or selecting from scroll.

Third I would like to display contact information in a form on the top of the page (from the selection from listbox) and at bottom a list of touchpoints that pertain to that contact from the touchpoints table.

Calling A Function From Form Submit?

Nov 21, 2010

I am trying to figure out how to call a function when a user clicks submit on a form.  I have a sample script that I am writing where the user inputs there name, address, etc.. and then clicks submit and it inserts into the mysql database.  I have successfully done this with form action to my adduser.php file, but I would rather have a single function file with adduser, delete a user, edit a user, etc..

here is my form

<form action="includes/customersfunctions.php?add" method="post">
name: <input type="text" name="name" /><br />
address: <input type="text" name="address" /><br />

[code]....

The function will have delete, update, etc.. later

Selection From A List Box.

Mar 28, 2006

php and have to implement this functionality to
select a user from a list box. I have written the code for this, but
the problem is after selecting a name and doing the required task, it
again selects the first entry in the list box. So if there are 100
users, the 100th one has to scroll down again and again.

I need to modify this code so that until the session expires, if a
person has selected his name once, that name will be selected in the
listbox until he changes it.

<select name="name" style="width: 120px;">
<?php
$query = sprintf("select * from person order by person_name");
$result = mysql_query($query);
$i = 0;
while($row = mysql_fetch_array($result))
{
$i++;
printf("<option
value="$row[person_num]">$row[person_name]</option>");
}
?>
</select>

Getting Id From A Selection List?

May 16, 2010

I have a parent table and a child table linked with an Id. The child table has two fields - ch_id and item. The parent table has a field which stores the value of ch_id for that row. I have set up a php script to generate a selection list in an html page.

The selection list only displays the text values of 'item'. Following a Submit the $_POST value will contain the text of the selected item. However, I want to store the ch_id value corresponding.A couple of ways that I can see, that I do not like, are - display the ch_id and the item text in the selection list and strip the id out before storing. This looks messy on the form; or do a reverse mySQL selection before updating the parent table.

Is there a smarter way to achieve this? In MS Access the list box can contain both fields with the id not displaying but being linked to the parent field.

Selection Of Records In List

Jul 16, 2005

I was wondering how to query MySQL to display only a selection (1-20,
21-40) of a query in an HTML list. Can that be done in an SQL
statement, or do you have to use PHP to dissect the returned array
with for n elements to n+20 elements. How does Google achieve the
returning of results in its search engine. I imagine that the same
query may not necessarily be executed each page listing. I am
wondering whether the results from the query would return an array of
say 36000 elements.

Multiple List Selection

Jul 24, 2007

I am still learning PHP, which is the best language for database driven sites. I am using Dreamweaver CS3 with the devleopers toolbox which is "ok" to help take the guess work out of things.

I am using a simple registration form that i made with the toolbox, but when I come to a multiple list to choose from (populated from the database) it doesn't work correctly. Of course, out of the multiple items selected only the last one gets inserted. From what I have read, the selection must be turned into an array then looped for this to work. Is this correct? Next how would I code this to work right.

Generated List - Date Selection?

Mar 18, 2009

I have created a page that shows a list of events and a drop down box to select which data I want to show.The event list shows

Date
Event Type
Event Name
Event Organiser
and two columns for remove and edit

The page works fine to show all entries in the database, but now I want to use the drop down select box to show data according to date and the following options

Full List, Past Events and future events

I could create 3 separate pages to get the results I want, but want to list them from this page.

I use this database coding for the full list

$query_rsEventDates = "SELECT * FROM growl_eventall ORDER BY eventDate ASC";

And I know that to select the past dates or previous dates I need to add 'WHERE eventDate > Now()' or 'WHERE eventDate < Now()'

I just need to know how to adapt what I have to use the list

Identifying User's Pick From Selection List

Jul 17, 2005

I have an application that uses PHP to access a MySQL table and
extract rows which match the user's search entry. Data from the
matching rows are loaded into an HTML selection list, and the user can
scan the list and highlight a selected item.

My question: In PHP, what is the syntax for identifying which row is
highlighted?

My goal is to pass the unique row ID of the selected item to a
subsequent form where all the fields will be displayed for the user to
edit.

I already have the code that loads the selection list and the code
that displays the fields. I just need to know how to determine the
highlighted item.

I have two PHP books, and both discuss loading the selection list, but
there is no mention of what to do next.

Create Dynamic Selection List For Class Registration?

Nov 10, 2010

I need some assistance with creating a dynamic selection list for class registration. Here is what I've go going: Case Use: Potential class takers fill out a form with contact information for a class. For the class selection there is a dropdown list containing the available classes. If the current date is past the first day of class then that class is not in the list. When a selection has been made the page will update and remaining seats available. If the class is full we are allowing two people to be put on a waiting list so the user will be given a check box to opt in or out. When the two standby seats are filled the option is no longer available.

Status: Currently every item mentioned in the case is working; however, I would like for any class that is full (including standby) to be omitted form the list along with classes that have already started.

Tables: courses - List of courses and dates offered (primary key: cid). registered - List of people register (primary key: rid, foreign key: cid).

Calling A Function From A Preg_replace Causes The Function To Load At The Top Of The Page?

Oct 31, 2010

We have some bbcode and I'm trying to setup the ability for a certain code to call a function that loads some images from our photo gallery. So if someone puts in an album number, it pulls 5 of the most recent photos out. When we call this function regularly (on another page, just as a regular php statement), it works as expected. But when we call this function through the preg_replace system, it loads the function at the top of the page.[URL] The pumpkin images at the top of the site should be within the news post, below "Thanks to Marcus M. for sending the news." - which is where I placed the bbcode [picvault]1[/picvault]

Here's how we change out the values for the bbcode

$newsPost = preg_replace(array_keys($bbcode), array_values($bbcode), $newsPost);
Here's the portion of the $bbcode that calls our function
"/[picvault](.*?)[/picvault]/e" => "relatedImages($1)",
And here's the relatedImage function
function relatedImages($albumID) {
$queryImage = mysql_query("SELECT * FROM cpg140_pictures WHERE aid = $albumID ORDER BY pid DESC LIMIT 5");
echo "<div class='relatedImages'>";
while($images = mysql_fetch_array($queryImage)) {

Calling A Function And A Javascript Function By Onclick Event?

Jul 18, 2010

I have a small problem and have been trying to figure out a solution for this without any success days. I did search the forum but didn't find any solution. This is my situation. I am generating a chart (using an opens source chart called amCharts) that allows me to zoom-in and and zoom-out of its X-axis by specifying the values by an onclick javascript function. To be more clear, my X-axis has values from Jan-01, Jan-02,till.Dec-31. I have a 'From' and 'To' input fields and a submit button. The user can specify any values and can zoom the chart to the specified dates. I have implemented this functionality using a javascript function.

Each day mentioned may have a few records associated with it that is stored in a MySQL database. My situation is that when the user submits, apart from zooming the chart, I also need to search the database and fetch records found between those two dates and display them in a separate frame in the same page. I think I can accomplish this with a PHP script.

Now how do I execute both a javascript function and a PHP function simultaneously when the user performs and an onclick event? Is it possible to execute javascript and php script together by an onclick event. Please let me know how. Is it possible to combine a server-side and client-side script function together in a function? Or should I use AJAX or something? If so how. I am totally lost.

Calling Usort From A Class Function - Comparison Function Go?

Jan 30, 2011

I need to call usort from a class function, and I'm puzzled about how to define the comparison function. I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me.

If I define the comparison function outside the class, it won't have access to object properties that it needs to operate. The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this?

Static Variable In Function Set By Calling Another Function?

Dec 7, 2010

I'm working in PHP. I have a function (F1) that gets called a variable amount of times. Within that function, I need to load a constant data set from another function (F2). It's always the same data set loaded, however loading the set involves some database lookups and processing. Rather than call F2 repeatedly and increase overhead/redundancy/processing requirements, I would like to put the result into a static variable in F1. However, for whatever reason, it will not allow me to set the variable as static using the function call.

A code example:

function calledRepeatedly() {
static $dataset = loadDataset();
// some minor processing here using the dataset
// and probably a loop
return "stuff";
}
function loadDataset() {

[Code]...

The above does NOT work. It results in an error -- unexpected '(', expecting ',' or ';' I do realize that it would work, and it would be passed by reference thus eliminating overhead, however that involves the extra work of making sure that calls to calledRepeatedly actually have the dataset in the arguments list.Is there any way to do this?

Multiple Selection In A Form

Jul 21, 2005

I have a form being generated from returned results from a basic db query. The problem I am having is when people are using the generated form - how to track what selection they have made. Example (output of partial form). Code:

<input type="text" size="2" maxlength="3" name="purchase[][qty]" value="0">
<input type="hidden" name="purchase[][price]" value="4.00">

Each item has six options (so imagine the above repeated six times for each item (total number of items can be determined, but there is no minimum or maximum). Anyway I have tried passing the above to another page (just to generate information) and I get nothing.
The code I am passing it to is . Code:

foreach ($purchase as $key => $price){
if($purchase[$key][qty] > "0"){
// whats nice is that you will have
// your values in the below hash
// and you can do you db stuff
echo $purchase[$key][price];
}
