Check If Form Is Submitted

Sep 26, 2001

I am using PHP to generate a form that submits to $PHP_SELF. The first time the script executes is should only create a data entry form based upon a MySQL "DESCRIBE table" statement. When submitted, the script will insert the form's data into a table using an INSERT INTO statement.

I need a way to determine if the script should DESCRIBE and generate the form or instead INSERT the submitted data into a table. In the past I used a hidden field with name=submitted value=true and checked for that to determine if script should DESCRIBE or INSERT.

However in this case I want to simply get the name/values from the HTTP header and INSERT them into the table. Form element names correspond to the desired table field names. Having the hidden field requires me to filter out the unwanted data. (I guess I need to submit the table name inorder to know which table to insert into, so there is atleast one required hidden field that is not part of the actual data to insert.)

How Do I Check If A Form Is Being Submitted?

I have a PHP code that checks if a form button has been clicked:

if (isset($save)){...
<input type="submit" name="save" value="Check the results...">

Upon clicking the button a PHP code runs that saves stuff to a MySQL db. The thing I'm doing is that I'm submitting the form with this code in a java script:


This javascript is triggered by other user input and I do Not want to force the user to press any additional buttons to submit the form. How can I make the PHP code run when submitting a form instead of a button? = I want to submit the form but After I've run my PHP code and saved my data to the db.

Check To See If File Was Submitted For Upload?

I'm trying to make a check to see if a file to be uploaded was added. I have tried the below and a few variations. I imagine I'm having problems because $_FILES is a global variable and is therefore always set. But I still can't figure out what to do instead.

if (!isset($_FILES['file'])){

Show The Non-selected Options In A Select Form After A Previous Form Is Submitted

I have a form where im asking for name, surname, phone cellphone and at the end user has to check one or more options in a checkbox and then clicks submit.

After that in the "thank you page" i want to show the exact form but this time to show only the non-checked checkboxes. Reason for this is that i want to say "We highly recommend you check all the options for better results, you can do so by simply clicking the submit button below"

And then below that i want to present the form as i said, but the remaining checkboxes (the oens that were not checked before) would be only the NON-checked options in the previous page. Makes sense?

Ive tried hard with php if states and switches but still cant get the result i want, it seems i have to define "false statements" in a way im not cabable of doing it.

Should i use php or jquery?

Submitted A Certain Form

I basically just need something that will, in an admin section of the site, tell how many times a certain form has been submitted. It's basically for a lead-generation counter for a real estate broker. The form would be something people would fill out to go into a home finding section, therefore, the broker could see how many leads were generated based on how many people filled out the form.

Submitted Form Just Shows Itself

I have a form i will use to register new people and when I click the
submit button, the form just shows itself. It is supposed to show a
message showing field errors if you leave fields blank etc. so
submitting the empty form should show error message in red , then show
form, but all it does is show form. I checked the variable to make
shore they ere ok and they are fine. i believe it is a logical error
with my if else.... I eved modularized everything by using functions
and the same results.

if any one sees the logical error, let me know. Here the code:


function showmessage() {
// Check to make sure they entered a valid email address.
if (eregi("^([[:alnum:]]|_|.|-)+@([[:alnum:]]|.|-)+(.)([a-z]{2,4})$",
$HTTP_POST_VARS['emailfield'])) {
$d = TRUE;
} else {
$d = FALSE;
$message1[] = "The email address you entered is not valid.";

function checkfields(){

$year = $HTTP_POST_VARS['yearfield'];
$month = $HTTP_POST_VARS['monthfield'];
$day = $HTTP_POST_VARS['dayfield'];
$dobfield = $year.$month.$day;
// Check the last name.
if (eregi ("^([[:alpha:]]|-|')+$", $HTTP_POST_VARS['usernamefield']))
$a = TRUE;
} else {
$a = FALSE;
$message1[] = "Please enter a correct username. I.e; EricDerouen
that consists only of letters.";

// Check the first name.
if (eregi ("^([[:alpha:]]|-|')+$",
$HTTP_POST_VARS['firstnamefield'])) {
