I saw a write up on how to do a HTML Array to PHP Array via form elements. I wish i could remember how it was done. I will keep searching and try to find it.


Found it: (Link for referrence)


4. How do I get all the results from a select multiple HTML tag?

The select multiple tag in an HTML construct allows users to select multiple items from a list. These items are then passed to the action handler for the form. The problem is that they are all passed with the same widget name. I.e. <select name="var" multiple="yes">

Each selected option will arrive at the action handler as: var=option1
var=option2
var=option3

Each option will overwrite the contents of the previous $var variable. The solution is to use PHP's "array from form element" feature. The following should be used: <select name="var[]" multiple="yes">

This tells PHP to treat $var as an array and each assignment of a value to var[] adds an item to the array. The first item becomes $var[0], the next $var[1], etc. The count() function can be used to determine how many options were selected, and the sort() function can be used to sort the option array if necessary.

The form retrieval element should look like this:

$arroffers = $_POST['offer'];

that's what I am doing

the error is Warning: Invalid argument supplied for foreach() in E:\hshome\\inboxphp\processform.php on line 21

consider the following simple example:

<?php
if (!isset($_POST['submit']))
{
    echo '
    <form action="" method="POST">
    please check numbers:<br>
    <input type="checkbox" name="numbers[]" value="1"> 1<br>
    <input type="checkbox" name="numbers[]" value="2"> 2<br>
    <input type="checkbox" name="numbers[]" value="3"> 3<br>
    <input type="checkbox" name="numbers[]" value="4"> 4<br>
    <input type="checkbox" name="numbers[]" value="5"> 5<br>
    <input type="submit" name="submit" value="submit">
    </form>
    ';
}
else
{
    if (isset($_POST['numbers']))
    {
        echo 'you checked the following numbers:<br><br>';
        foreach ($_POST['numbers'] as $value) {echo $value . '<br>';}
    }
    else
    {
        echo 'you did not check any numbers';
    }
}
?>
