stuck. multiple buttons.. how to get the data for the one pushed?

[ecg]

Hi..
I have a setup of:
input text, button, checkbox
input text, button, checkbox
input text, button, checkbox
input text, button, checkbox
input text, button, checkbox
etc

The idea is that I enter some data and tick the checkbox (or not).. then press the button to validate the data...

what I have at the moment is:

$Data = array(array text => "first", ticked => 't'));

for ($i = 0; $i<10; $i++){ 
<td><input type="text" name="Text[$i]" size="15" value="<?php echo $Data[$i]["text"] ?>"></td>
<td><input type="button" value="Validate Text" class="InputButton" 
onClick="FormChangeAction('Validate'); FormSubmit();"></td> 

(ie javascript that says action = validate)

<td><input type="checkbox" name="Print[$i]" <?php if ($Data[$i]["ticked"] == "t") echo " checked" ?>></td> }   

So if theres no data in the array a blank input text box and an empty checkbox appear.

Say I enter data into the 3rd box down.. and press the button... how do I say "3rd button was pressed get Text[3]"??

Any ideas?

If the checkboxes have different names, you can just test to see if that variable exists and then validated the corresponding text input. Or, if each field has its own button, nix the checkboxes entirely and just test for which button was clicked.

Thanks for your reply Sarah.

I could just name all 10 of the buttons... but the set of data is liable to grow in the future... so I might have 20 buttons...or 30....

so if its possible I'd like to use an array and loop through...

but I've been looking and looking and can't figure out how to do it...

Any Ideas???

Thanks
Beth :-)

Maybe just name the buttons...
<input type="submit" name="Submit" value="submitTextfield1">
<input type="submit" name="Submit" value="submitTextfield2">
<input type="submit" name="Submit" value="submitTextfield3">

Then, after the button has been clicked, do something like...

$thingToValidate=preg_replace("submit","",$Submit);
validateFunction($thingToValidate);

I am sure there is a better way to do it, but without knowing the function of your script or what you are trying to validate, this should get you going.

If I understand your posting then what you want to do is to add a value attribute to the checkbox element.

<input type="checkbox" name="Print[]" value="$i">

Then
$boxes = $POST['Print'];
$texts = $POST['Text'];
foreach($boxes as $i)
{
echo "Checked $i $texts[$i]";
}

Only the boxes that were checked will get returned. You only need one button to submit all the checked items.

Thanks for the reply Ahundiak.

I need to know which button was pressed and to get the values of the textbox and checkbox.
I'm trying to be smart and put them in arrays etc...
I will 'play' with the name and value attributes... thank you for that pointer....

But why do you need a button and a checkbox for each text.

And if you do really want a button for each record then make each record into it's own form and don't arrays at all. You can store the record id in it's own hidden field if you really want to.

I think the form idea may be the one to go with.. will let you know how I get on. Had played with the idea yesterday... but for all 10 records within the form rather than each seperately...

try and try again huh??
Thanks for the help :-)

PS. if you're interested....this is what I want to do....
on my screen I'm creating a set of keywords (the text part) and for each I want to say whether if prints or not (the checkbox).
the button exists to perform validation on the keyword (by checking if it exists in a table) and then send the user to choose an image to go with the keyword.
my tables look like:

images
imageid
imagename
pic

keywords
keywordsetid
imageid
keyword
print

keywordset
keywordsetid
keywordsetname
...

validkeywords
keyword

and images can have multiple keywords and keywords can have multiple images so until I have the imageid, the keywordsetid and the keyword I don't really want to save to the table (hence the arrays etc)...

However.. any better ideas would be greatly appreciated :-)
