Simple Problem: Drop Down Box - How? - HTML Forums

Curver · 10-31-2009, 05:54 AM

Hello i have a simple problem, i am wanting to make a drop down box which selects a value automatically:

<select size="1" name="decision" value="<?php if(isset($results[0]['decision'])){ echo validHTML($results[0]['decision']);} ?>">
<option selected value="">-</option>
<option value="1">Yes</option>
<option value="0">No</option>
</select>

As you can see, the drop box options are fixed but i want it to select the value which has already been selected by the user in the database but it seams the value attribute dosnt work.

How do you do this?

Thanks,
Curver

The select tag doesn't make use of the value attribute so remove it.

In your code you have selected the value, the first one in fact. You need to do your test for selection for each option i.e.

PHP Code:


			
<select name="decision">

<option <?php echo (isset($results[0]['decision']) && $results[0]['decision'] == 1 ? 'selected="selected" ' : '');?>value="1">Yes</option>

<option <?php echo (isset($results[0]['decision']) && $results[0]['decision'] == 0 ? 'selected="selected" ' : '');?>value="0">No</option>

</select>

On another note, you shouldn't leave the option of "blank" to the user unless the blank option is a viable option - in this case, where the answers should only be Yes or No, this wouldn't be correct.

Thank you for your help.

I have since found a solution:

HTML Code:

<!--webbot bot="Validation" b-disallow-first-item="TRUE" --><select size="1" name="decision">
		<option value="">-</option>
		<option value="1">Yes</option>
		<option value="0">No</option>
		</select>
</td>
		<script type="text/javascript">
		document.form1.decision.value = <?php if(isset($results[0]['decision'])){ echo validHTML($results[0]['decision']);} ?>;
		</script>

The reason i left a blank field is that i didnt want users to be lazy and no select an option. It is not as simple as "have you read our terms yes/no" where it can default to no. This is somthing which can be either a yes or a no option and the user must be promped to make a selection.
