[Resolved] multipart/form-data

paul_mac

By adding ENCTYPE="multipart/form-data" to the form definition I seem to have lost the data from a hidden field in the form when the page calls itself so that when I do a

if (isset($POST['ok2Do'])){$okToDo = $POST['ok2Do'];}

then the valiable $okToDo is no longer available

The full definition is

<FORM METHOD="POST" ACTION="<?=($PHP_SELF)?>" NAME="press" ENCTYPE="multipart/form-data">
<INPUT TYPE="hidden" NAME="ok2Do" VALUE="no">

I'm using ie5.5. The file is getting too long to post as it now runs to over 500 lines and I'm not sure which bits above what I've posted will help you.

The file starts with:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<?php
if (isset($POST['ok2Do'])){$okToDo = $POST['ok2Do'];}
if (isset($POST['what2Do'])){$whatToDo = $POST['what2Do'];}
if (isset($POST['lineNum'])){$lineNum = $POST['lineNum'];}
if (isset($POST['dataCell1'])){$newDataCell1 = $POST['dataCell1'];}

and then fails at line 58 with

if ($okToDo == "yes"){

The form definition is
<FORM METHOD="POST" ACTION="<?=($PHP_SELF)?>" NAME="press" ENCTYPE="multipart/form-data">
<INPUT TYPE="hidden" NAME="ok2Do" VALUE="no">
<INPUT TYPE="hidden" NAME="what2Do" VALUE="none">
<INPUT TYPE="hidden" NAME="lineNum" VALUE=0>

The other 2 variables are preserved, I've just checked them.

The submit button for the form calls a javascript function prior to the sumbit

I've checked document.press.ok2Do.value and it is correct prior to the page reloading

<INPUT TYPE="hidden" NAME="ok2Do" VALUE="no">

u set the value of ok2Do to "no" and later on in your script, u check if $okToDo == "yes".... cannot work, or do i misunderstand your code?? was just my first idea in order to make sure it's not this simple problem... so if i am wrong, tell me, then i will keep on checkin your code, else your problem is resolved...

It's not the value of the variable, its the fact that the variable is no longer available.
I'm not the only one to have this problem - see http://www.experts-exchange.com/Web/Web_Languages/PHP/Q_20689359.html but I don't fully understand how that person resolved it. I don't have access to the php.ini file, that's the property of the hosting company isn't it?

Also I've got a separate file upload rountine that works on its own - I was testing it out before integrating it into the main page that I was building.

First thing I did was add the enctype=multipart/form-data attribute and everything stopped working.

ok i read it so are u sure u may use file uploads?? call the phpinfo() function and check whether the config option file_upload is set to on....

Hi, problem sorted.

Firstly, yes I do have permission to upload files but I can't run phpinfo(), the hosting company has dissabled it for security reasons.

The page, which as I said is quite large, accesses a flat textfile database and displays the information about a group of companies.

The data can be displayed in one of 3 formats:
1) A simple list/table with 3 columns,
2) A more detailed list with all the database record info deplayed for editting
3) A new blank record ready for inputting data for a new entry.

When the page first loads it diplays the info in format 1)

The user can then select to edit a record - format 2) or input a new record - format 3). When format 3 is used there is a field to upload an image file - which is why I added the 'enctype=multipart/form-data' attribute.

So I changed the form definition to:
<FORM METHOD="POST" ACTION="<?=($PHP_SELF)?>" NAME="press" <?if ($brandNew == "yes"){echo "ENCTYPE='multipart/form-data'";} ?>>

where $brandNew is a new variable to define if a new record is being added. In this case the field for the image file is then also part of the form definition. I've also added a hidden field <INPUT TYPE='hidden' NAME='MAX_FILE_SIZE' VALUE='20000'> that is only present when the image upload field is present.

It would appear that if the "ENCTYPE='multipart/form-data" attribute is added to the form tag then the file upload field also has to be present - not sure about the MAX_FILE_SIZE.
