radio group retaining value on failed validation

Hi Ray

On the attached page, am trying to retain the selected value of the radio group starting at line 263 when validation fails but am not having an joy at all and not sure what I have done wrong?

Cheers

Form element names can't have spaces in php. I think it automatically renames them to use underscores, so instead of:
ValidatedField("contactform","Legal Aid Qualify")

try:
ValidatedField("contactform","Legal_Aid_Qualify")

You may just want to avoid underscores in form element names in general to prevent having to do work-arounds like this.

Thanks Ray but I had already tried Legal_Aid_Qualify, LegalAidQualify all with no positive result.

OK... I see that on the second radio you have:

<input <?php if (!(strcmp((ValidatedField("contactform","Legal Aid Qualify")),"no"))) {echo "checked=\"checked\"";} ?> name="Legal Aid Qualify" type="radio" id="Legalaid_1" value="no" checked="checked">

since it has a hard-coded: checked="checked" and only one radio can be checked at a time, the dynamic selection will be ignored and the second one will always be checked.

probably the best solution is to update it to:
<input <?php if ((strcmp((ValidatedField("contactform","Legal_Aid_Qualify")),"yes"))) {echo "checked=\"checked\"";} ?> name="Legal Aid Qualify" type="radio" id="Legalaid_1" value="no" >

That way it is the opposite of the first radio and one or the other will be checked.

thanks Ray. that just selects both radios on a failed validation. I'm just going to not preselect any checked value and add validation for each radio group

thanks a million though

It should never be possible to select two radio button values at the same time if they have the same name. The browser prevents that. Let me know if you want me to take another look, but I think my solution should have worked. I'd have to take a look at the updated page to see what was wrong with the implementation.
