Question

I have the following code:

<?php
$allform = $_POST['allform'];
parse_str($allform, $output);

$allquery = "SELECT * FROM wp_users";
$names    = array();
$allresult = mysql_query($allquery) or die(mysql_error()); ?>

...

<?php

while ($rows = mysql_fetch_array($allresult)) {

    $names[] = $rows['user_email'];

}
?>

The allform variable is a jQuery serialize string:

var allform = $('form#all').serialize();

Basically, I want to put the values from the form in the front end into a mysql select query in the back end.

The form is a bunch of checkboxes so the idea is that the SELECT something will have different number of values depending on what the user checks. Any ideas?

Thanks

The best thing to do could be something like this. Your checkboxes should be like this

<input type="checkbox" name="checkboxes[]" value="cream" />
<input type="checkbox" name="checkboxes[]" value="choco" />
<input type="checkbox" name="checkboxes[]" value="lime" />

server side you receive an array

$flavours = $_POST["checkboxes"];
$sql = "SELECT ".implode(',', $flavours)." FROM FLAVOURTABLE";
