Getting radio button values from POST

[jedimastafez]

Hi guys, I normally wouldnt ask for help but I have googled this for a week and none of the stuff I found seem to fit what I need.

So if anyone can help with this it would be greatly appreciated.

Im doing a family photo album and have the forms all set up but have come across one small problem.

I have the form display five fields for five photo uploads, they write a caption for the photo, select the photo and check a radio button if they wish the photo to be the "Cover" photo for the current album they are uploading it too.

The problem I have is the form calls "upload.php" which grabs all the necessary values from POST, but I am stuck as to how to grab the value pertaining to which radio button is checked.

Does anyone know how best to do this?  All I can find is a javascript but if I do that how do I translate the returned javascript function value into a php variable to be sent through POST and retrieved in the upload.php form.

Again any help you could offer would be awesome.

[code]echo $_POST["<radio button name>"];
[/code]

Name the radio buttons the same, but give them different values.

e.g:
[code]
<input type="radio" value="Cover" name="type">
<input type="radio" value="Non-Cover" name="type">
[/code]

Then on form.php:
[code]
$type = $_POST['type'];
[/code]

thanks for the suggestions guys, impulse() I already tried that.  It doesnt print out anything when I do that.  Ofcourse I have not set the values to anything which leads me to your pointer hostfreak.

I cant assign a "cover" "non cover" thing because I dont know which they will pick to be the eventual cover

Here is the HTML

[code]<div id="addPhoto">
<br>
<input type="hidden" name="photoNumber0" value="new">
Caption:<br>
<input type="text" name="photoCaption0" size="60"><br>
File:<br>
Is Cover Image:
<input type="radio" name="isCover" checked>
<input type="file" name="photoFile0"><br>
<input type="hidden" name="photoNumber1" value="new">
Caption:<br>
<input type="text" name="photoCaption1" size="60"><br>
File:<br>
Is Cover Image:
<input type="radio" name="isCover">
<input type="file" name="photoFile1"><br>
<input type="hidden" name="photoNumber2" value="new">
Caption:<br>
<input type="text" name="photoCaption2" size="60"><br>
File:<br>
Is Cover Image:
<input type="radio" name="isCover">
<input type="file" name="photoFile2"><br>
<input type="hidden" name="photoNumber3" value="new">
Caption:<br>
<input type="text" name="photoCaption3" size="60"><br>
File:<br>
Is Cover Image:
<input type="radio" name="isCover">
<input type="file" name="photoFile3"><br>
<input type="hidden" name="photoNumber4" value="new">
Caption:<br>
<input type="text" name="photoCaption4" size="60"><br>
File:<br>
Is Cover Image:
<input  type="radio"name="isCover">
<input type="file" name="photoFile4"><br>

<input type="submit" onClick="" value="Add photo">

</div>[/code]

And a screenshot (this is only a rough design and layout)

when it comes time to grab the value from the radio buttons from POST I use this

[code]$isCover = $post_safe["isCover"];
echo $post_safe["isCover"];[/code]

Where $post_safe is the original POST data with slashes added

any other suggestions?

You could try this.....  :-\

Form.html
[code]
//Image and other data
<input type='radio' name='WhichImage' value='Photo1'>Use as Thumbnail
//Image and other data
<input type='radio' name='WhichImage' value='Photo2'>Use as Thumbnail
//Image and other data
<input type='radio' name='WhichImage' value='Photo3'>Use as Thumbnail
//Image and other data
<input type='radio' name='WhichImage' value='Photo4'>Use as Thumbnail
//Image and other data
<input type='radio' name='WhichImage' value='Photo5'>Use as Thumbnail
[/code]


Processing.php
[code]
if (!isset($_POST['WhichImage'])){
  $WhichImage = "Photo1";
}
//If WhichImage variable is not set, default to Photo1 for the thumbnail

else {
  $WhichImage = $_POST['WhichImage'];
}

//Otherwise use the WhichImage variable
[/code]

Sorry not checked my code but I'm fairly sure this works in theory!!
