How to maintain the users list box selection on post?

[altergothen]

Hi Guys

I am trying to maintain the users list box selection after posting.
How can I get this script to work?
Is there perhaps a better way of doing this?

<?php

$mySelectOption['1'] =
$mySelectOption['2'] =
$mySelectOption['3'] =
$mySelectOption['4'] =
$mySelectOption['5'] =
$mySelectOption['6'] = '';

if(!empty($_REQUEST['mySelect'])){
$mySelectOption[$_['mySelect']] = 'selected';
}else {
$mySelectOption[1] = 'selected'; // Default selected, for first time
}
?>

<form name="myform" action="mySelectOption.php">
<select name="mySelect">
<option value="1" <?=$mySelectOption['1']?> >option1</option>
<option value="2" <?=$mySelectOption['2']?> >option2</option>
<option value="3" <?=$mySelectOption['3']?> >option3</option>
<option value="4" <?=$mySelectOption['4']?> >option4</option>
<option value="5" <?=$mySelectOption['5']?> >option5</option>
<option value="6" <?=$mySelectOption['6']?> >option6</option>
</select>
<input type="submit" name="submit" value="Submit">
</form>

I sort of managed to get it working like this, but only if I the value is in a specific numerical order. ...Is there a better solution?
[php]
<?php
if(isset($_POST[mySelect])){
$mySelect = $_POST[mySelect];

switch($mySelect){
case 1:
$mySelectOption[1] = 'selected';
break;
case 2:
$mySelectOption[2] = 'selected';
break;
case 3:
$mySelectOption[3] = 'selected';
break;
case 4:
$mySelectOption[4] = 'selected';
break;
case 5:
$mySelectOption[5] = 'selected';
break;
case 6:
$mySelectOption[6] = 'selected';
break;
default:
$mySelectOption[1] = 'selected';
}
}
?>

<form name="myform" method="post" action="mySelectOption2.php">
<select name="mySelect" id="mySelect">
<option value="1" <?=$mySelectOption['1']?> >option1</option>
<option value="2" <?=$mySelectOption['2']?> >option2</option>
<option value="3" <?=$mySelectOption['3']?> >option3</option>
<option value="4" <?=$mySelectOption['4']?> >option4</option>
<option value="5" <?=$mySelectOption['5']?> >option5</option>
<option value="6" <?=$mySelectOption['6']?> >option6</option>
</select>
<input type="submit" name="submit" value="Submit">
</form>[/php]

Please enclose any code within the proper code tags. See the Posting Guidelines on how to do that.

Best way to do is is to echo the 'selected' attribute, after testing the $_POST, in your form. When the $_POST is not set, iut is the first pass and option 1 will be set to selected (default).

See this code:
[php]<?php
if(isset($_POST[mySelect])){
$mySelect = $_POST[mySelect];

switch($mySelect){
case 1 : // process
break;
case 2 : // process
break;
case 3 : // process
break;
case 4 : // process
break;
case 5 : // process
break;
case 6 : // process
break;
default: // process
break;
}
}
?>
<form name="myform" method="post" action="a.php">
<select name="mySelect" id="mySelect">
<option value="1" <?php if(!isset($_POST['mySelect']) OR $_POST['mySelect']==1) echo "selected"?> >option1</option>
<option value="2" <?php if($_POST['mySelect']==2) echo "selected"?>>option2</option>
<option value="3" <?php if($_POST['mySelect']==3) echo "selected"?> >option3</option>
<option value="4" <?php if($_POST['mySelect']==4) echo "selected"?> >option4</option>
<option value="5" <?php if($_POST['mySelect']==5) echo "selected"?>>option5</option>
<option value="6" <?php if($_POST['mySelect']==6) echo "selected"?> >option6</option>
</select>
<input type="submit" name="submit" value="Submit">
</form>[/php]
