[RESOLVED] sending multiple variables as one & parsing

[BEFOR]

There are three url parameters combined into one ( HTTP post) that are each seperated by a colon, For example:

&ThreeField=500:700:800

Where the values are:

<?php echo $row_query['X']; ?> :<?php echo $row_query['Y']; ?> : <?php echo $row_query['Z']; ?>

• how can these be formatted, to be passed as url variable with:

<input type="hidden" name="ThreeField" value="?">

(b) Then, when I receive ThreeField as a postback, how can parse these out into their three local variables, as independent values, in the form:

$X_value = $POST['ThreeField'];
$Y_value = $POST['ThreeField'];
$Z_value = $_POST['ThreeField'];

[bradgrafelman]

<input type="hidden" name="ThreeField" value="<?PHP echo $row_query['X'] . ':' . $row_query['Y'] . ':' . $row_query['Z']; ?>">

Then, use [man]explode[/man] to separate the string on a colon to get your three values back.

Appreciate it, bradgrafelman
