 Subject: [PHP]I'm puzzled. TEXTAREA related.
 
 
 hey-
 
 i have a page containing a form with a textarea field. The 
 first part of the page is a quick IP check to make sure the
 request is coming from my computer. Here's the code I'm
 confused about:
 
 
 textarea rows=25 cols=80 name=news_info [snip]
 ?php
 readfile(lib/news_file.dat);
 ?
 /textarea
 brbr
 input type=submit name=submitnbsp;nbsp;
 input type=reset name=resetbr
 
 -this part above reads in data from the news file and it's 
 put in between the textarea tags, so editing it is easier,
 then there is this part:
 
 ?php
 }
 
 if($submit)
 {
 $fileh = fopen(lib/news_file.dat, w);
 fwrite($fileh, $news_info);
 fclose($fileh);
 }
 ?

Assuming the order of events in your script is as described above,
here's what's happening:

1st request: 
script displays textarea (blank, or with old contents)
$submit is unset, so no further action

2nd request:
script displays textarea (blank, or with old contents)
$submit is set, so *now* we write the new data out to the file

3rd request:
script displays textarea with updated contents

So...I'd expect the answer is to make sure you're updating the file
*before* you look at its contents.

 ?php

 /textarea
 brbr
 input type=submit name=submitnbsp;nbsp;
 input type=reset name=resetbr

 if($submit)
 {
 $fileh = fopen(lib/news_file.dat, w);
 fwrite($fileh, $news_info);
 fclose($fileh);

 - that checks if the submit button was pressed, and if so, it writes
 the data from the textarea to the file
 - the problem I noticed was that if I submit with something in the
 textarea, it doesn't display when the page loads again, which is weird,
 because the action of the form is directed to the same page. but, if I
 press submit an addditional time, the data I entered in the first time
 comes up...I don't understand why it's not immediately showing up,
 since it does write to the file when submit is pressed

 please help!

You aren't setting a value for submit, so you might be better checking 
for either isset($submit) or !empty($submit) rather than if($submit). 
Otherwise try assigning a value to submit in the input tag.
