[SOLVED] Using if (isset($_POST['ap_nmF'])) on radio buttons


Recommended Posts

How do I do this: [code]<input size="20" name="ap_nmF" value="<?php if (isset($_POST['ap_nmF'])) echo $_POST['ap_nmF']; ?>" />[/code]
on a "radio" button, when all the radio buttons use the same name?
<input type="radio" class="radio" name="ap_bnk1" value="Apple">
<input type="radio" class="radio" name="ap_bnk1" value="Grape">
<input type="radio" class="radio" name="ap_bnk1" value="Orange">
<input type="radio" class="radio" name="ap_bnk1" value="Pear">

Any help would be apprechiated?

I have a form, that if required fields arent inserted and error page displays telling the user to complete the required fields. Problem is that when the user clicks back to correct the problems all the data is lost. I figured out that on a text box you can use
[code]<input size="20" name="ap_nmF" value="<?php if (isset($_POST['ap_nmF'])) echo $_POST['ap_nmF']; ?>" />[/code] and it will hold  the information, but how do you do the same type thing on a radio button if all the radio buttons use the same name, just have different values?

The page I'm working on is here. [url=http://www.carcityofdanbury.com/apply.php?applicant=single]http://www.carcityofdanbury.com/apply.php?applicant=single[/url]

(Hopefully my explanation helps...)

Do you ppl code?

He's trying to get the value of his radio choice into a text field.

Bookatay,  what you have should work if POST['ap_nmF'] is set.  Is It ?
create an ELSE and see what happens..

I like how you acted like we were morons yet you were wrong.

DBookatay rather than have an error page, just have the errors appear on the same page as the form. Keep all the previously submitted info in variables and set them as the inputs values so the info is not lost. There is no need for an isset, as the input will just be blank if it isn't set. If they didn't put in a value then the box will be empty.

If you mean you want the same radio button selected as the one they previously selected then make a variable for each one, and if that was the previously selected one set it as "CHECKED".


[code]if ($_POST['ap_bnk'] == "Apple") {
$radio1 = "CHECKED";

and put the relevant variable in the end of each radio button.


[code]echo <<<HERE
<input type="radio" class="radio" name="ap_bnk1" value="Apple" $radio1>
<input type="radio" class="radio" name="ap_bnk1" value="Grape" $radio2>
<input type="radio" class="radio" name="ap_bnk1" value="Orange" $radio3>
<input type="radio" class="radio" name="ap_bnk1" value="Pear" $radio4>
