php drop-down

[jefargrafx]

I've created an html drop down that is populated via an sql qurry.

simple

the select field is name in_review

and I have a onChange="this.form.submit(); which submits the form to the same php page. Okay that'll work if I use hidden field to hold the results, but I'd like the drop down to remember it's selection.

how is this done? $HTTP_GET_VARS['in_view'];

any help?

jef,

If you can collect the selected field in PHP ( I'd do this:

$in_view=$_REQUEST["in_view"];

). Then you can add selected="selected" in the option tag for the selected option...

Good Luck §;O)

Can you elaborate a bit...I'm got a similar problem..
I've got a drop down box that the user completes. After completing the form, the user hits the submit button and the application lets him/her know what fields haven't been completed properly. The problem is that even though I've completed the drop down box field (in this case, it's the state), the state doesn't appear on the screen when the form is called again. Help!!!!

here's how I fixed it

<select name=&quot;in_review&quot; id=&quot;in_review&quot;onChange=&quot;this.form.submit();&quot; >
<?php
do {
?>
<!-- <option value=&quot;<?php //echo $row_rs_in_review['code']?>&quot;<?php //if (!(strcmp($row_rs_in_review['code'], $row_rs_in_review['code']))) {echo &quot;SELECTED&quot;;} ?>><?php //echo $row_rs_in_review['code']?></option>-->
<option value=&quot;<?php echo $row_rs_in_review['code']?>&quot;<?php if (!(strcmp($HTTP_POST_VARS['in_review'], $row_rs_in_review['code']))) {echo &quot;SELECTED&quot;;} ?>><?php echo $row_rs_in_review['code']?></option>
<?php
} while ($row_rs_in_review = mysql_fetch_assoc($rs_in_review));
$rows = mysql_num_rows($rs_in_review);
if($rows > 0) {
mysql_data_seek($rs_in_review, 0);
$row_rs_in_review = mysql_fetch_assoc($rs_in_review);
}
?>
</select>


notice the $HTTP_POST_VAR['in_review'], it works great accept when the page is first displayed.

so in the head I added

$in_review = $in_review


it's a hack, but working



also, on the $_REQUEST['field']

does this work even on the same page when posting back to itself? very cool

Excellent! Yes, it works on the same page.
