Warning: Extract(): First Argument Should Be An Array In


Sep 25, 2003

I'm creating a program to edit the details of members of an executive committee stored in a MySQL database. However, I recently have started getting the following error:

Warning: extract(): First argument should be an array in (lists file name and location of error)

To give a little background, the user selects the member to be edited from a drop-down list, which then passes the execID associated with that position to this program, which then queries the table for all the details of that particular member. However, I get the above mentioned error located to the line after "extract($row)".

I'm sure the solution to this is obvious to more experienced users, but I am baffled as I have used an almost identical setup for another project without experiencing the same error. I appreciate that the results of a query are loaded into an array, but I don't understand why a one-row result should cause such an error. PHP Code:

Warning: Array_multisort() [function.array-multisort]: Argument #1 Is Expected To Be An Array Or A Sort Flag

the following code produces the error in the title. I've tried to google it, but all I got were pages who got the same error (and not an explanation thereof). This isn't really a problem since it's actually working and cancelling the error out with the @ works out just fine. Though I'm still wondering why I haven't been able to execute array_multisort just once without getting this error.

public function getMostRelevant(){
list($occurrences, $keywords) = $this->occurr_keyw_array;
array_multisort($occurrences, SORT_DESC, SORT_NUMERIC,

Missing Argument Warning

I'm getting an error saying an argument is missing, even though it appears to be read correctly by the function:

Warning: Missing argument 9 for myfunction() in path/myscript.php on line 103

But argument 9 is then read and used correctly in the function. As a temporary 'solution' I've just suppressed the error by prepending a '@' to the function name when called, but I'm at a loss to understand this.

Invalid Argument Warning

I'm getting a Warning: Invalid argument supplied for foreach() error message for this bit of code:

foreach($_POST['healthConditions[]'] as $key=>$value) {
if($count > 1){
$_SESSION['saFormData'] .= " $value, ";
$count--;
} else {
$_SESSION['saFormData'] .= " $value.<br>";
} }

I've done some research that said that this warning either means you've got a string instead of an array or that the array is null. Mine is obviously an array because its data that's being passed from a form via post.

However, the warning goes away if a user has checked any of the healthConditions boxes so I guess it's because the array can be returned as NULL if they don't check any. I tried putting

$_POST['healthConditions'] = array("");

and even

$_POST['healthConditions'] = array("anything");

The way the form is worded, the user needs to have the option of leaving all checkboxes blank.

what is the correct syntax for 'parent::WP_Widget' using namespaces?

Warning: Invalid Argument Supplied For Foreach()

I'm getting a Warning: Invalid argument supplied for foreach() r from this line of code

foreach ($fileContent as $line) {

The only thing I can figure is this line of code may be causing the error. I've never seen a line like this in a PHP class file.

$fileContent = @file($this->RATES_RESULT_FILE);
function readRatingList($item) {
$i = 0;
$output = array();
// Convert item value to lowercase to make it case insensitive $item = strtolower($item);
// Open the file contains the current ratings
[Code]....

This code is part of a class that is used in conjunction with a javascript file to rate articles.

Warning: Mysql_num_rows(): Supplied Argument Error

I'm receiving the error above in my shopping cart application. I sell one-off items and use Paypal as the payment engine. In the remote possibility an item was previously purchased I loop through each order and update one at a time. I'm counting rows so if a record is not updated, I'd like to know. Strangely, it's working as designed (sending emai), but don't want to deploy unless I know why this error is occuring.

Here's what I've got so far. Here's the full error:

1. :confused: is not a valid MySQL result resource in cartworks15.php on line 105.

2. Do I need to change the variable to a different function. Is my syntax correct. Code:
