passing multiple fields to write to a file

Spud_Nic

I've got a php page, which reads data from a txt file, using $GetLine[1] etc variables. The data from the file is then put into form text fields, named Name, Email, Comments. This is looped until the whole file is read, and there's lots of text fields named "name", "email" etc within one form.

I then want to "submit", after possibly editting the fields and write to file.

Obviously I can't have several fields with the same name in the same form, but not sure how do get it to work!!!! I've tried using arrays, so each set of fields in the form is named "Name[1], Name[2]" etc but I don't know how to handle that when this has been submitted!

Can anyone help?

Thanks

Change the form element names acording to the loop iteration. ie

<?php
for($i=0;$i<count($results);$i++) {
?>
<input type="name<?=$i?>" value="<?=$results[$i]['name']?>" />
<?php } ?>

The setup here is nothing like yours but the idea should be roughly the same.

thanks for that, and i've got something like that already, but it's not working because I don't know how to handle that once it's submitted.

So for instance, Name[1], Email[1], Comments[1] will be submitted, along with Name[2], Email[2], Comments[2].

But how can I get the php to recognise this and write all the [1]'s to file, then append the [2]'s, then the [3]'s etc??

Assuming you used this to create the form:

 <?php 
for($i=0;$i<count($results);$i++) { 
?> 
<input type="name<?=$i?>" value="<?=$results[$i]['name']?>" /> 
<?php } ?>

You would get data from the form like this:

for ($1=0; $i < count ($results); $i++)
{
     echo $_POST["name".$i];
}

Sine in the form elements were named name1, name2, etc etc... you can recall them in the same manner, by specifying name1, name2, etc. if $i = 1, then $POST["name".$i] is the same as $POST["name1"].

My code I'm using differs slighty, here's what I have:

<?
for ($n=0; $n < count($Data); $n++) {

$GetLine = explode("|~~|", $Data[$n]);

?>

<input name="Name<?=$n?>" type="text" value="<?=$GetLine[0]?>">
<input name="DateSave<?=$n?>" type="text" value="<?=$GetLine[3]?>">
<input name="Email<?=$n?>" type="text" value="<?=$GetLine[1]?>">
<input name="Homepage<?=$n?>" type="text" value="<?=$GetLine[4]?>">
<textarea name="Comments<?=$n?>"><?=$GetLine[2]?></textarea>

so, using what you've suggested, I've altered it to:

for ($n=0; $n < count ($Data); $n++) {
echo $_POST["$GetLine.$n"];
}

but this doesn't work!!!! I think I must be close to getting it working... just not quite there!!!!

Any suggestions?

when you have echo $_POST["$GetLine.$n"];, your telling php to look for a form element named $GetLine.$n, instead of telling it to look for a form element named Name1 ("Name".$n).

<? 
<input name="TotalAmount" type="hidden" value="<?=count ($Data);?>">  <- this is here so you know how many items you were originally dealing with
for ($n=0; $n < count($Data); $n++) { 
$GetLine = explode("|~~|", $Data[$n]); 
?> 

<input name="Name<?=$n?>" type="text" value="<?=$GetLine[0]?>"> 
<input name="DateSave<?=$n?>" type="text" value="<?=$GetLine[3]?>"> 
<input name="Email<?=$n?>" type="text" value="<?=$GetLine[1]?>"> 
<input name="Homepage<?=$n?>" type="text" value="<?=$GetLine[4]?>"> 
<textarea name="Comments<?=$n?>"><?=$GetLine[2]?></textarea> 

This is where the page gets submitted, and the form data is sent to another page


This is where the other page starts, and grabs data from the previous page

for ($n=0; $n < $_POST["TotalAmount"]; $n++)
{ 
	echo $_POST["Name".$n]; 
	echo $_POST["DateSave".$n]; 
	echo $_POST["Email".$n]; 
	echo $_POST["Homepage".$n]; 
	echo $_POST["Comments".$n]; 
}

thanks, its helping me make a lot of progress!!

however, the second page still doesn't recieve the passed form information... the page loads, but there's nothing on it - the php isn't excuted.

the echo $_POST["Name".$n]; does seem to make sense to me, but obviously isn't working! :-s

can anyone see why?

Post your pages so I can see what you have.

here's the two files i'm using. they're part of other pages, but its just these two files which are used for the passing of form variables which I'm trying to figure out!!!!!!

I've been playing on with the second file where it would echo the results, but no luck so far! :-s
