pfffft - some trouble with form input and PHP

[g0rm4n]

Hello, hope that someone is able to help me.

I have two years of programming experience, one with BASIC and one with C++, and know a fair deal about some of the basic concepts, but I'm getting stumped by a really minor problem (hopefully).

Let's say I have an HTML document with the following FORM code:

<form method="post" action ="parse1.php">
<input type="text" name ="user">
<input type="submit" value="hit it!">
</form>

Then these are the relevant contents of parse1.php:

<?php echo "Welcome <b>$user</b><P>\n\n"; ?>

Only "Welcome" is printed, any ideas why? :\

Because you mos tlikely have globals set to off. $user isn't a global. To access it, you'd need to use $_POST["user"]

<? echo "Welcome <b>" . $_POST["user"] . "</b><P><br><br>"; ?>

Also, \n won't produce html breaks. it will add newlines in your code, but as you already know, you can hit return as many times as you'd like in your html source and it's still displayed as one long line. You have to use <br> to actually display a break on the visitors browser.

Hope this helps.

thanks man, i'm going to test it out right now, i'll let you know if it works.

it does work but i'm going to use global variables for now because it saves me some typing and i'm not dealing with anything that needs security 😃

well, i've spent about an hour coding some things, just trying to get a feel for the language...

i'm hoping to eventually get an automated news system with updates via an admin form input... have to figure out files before i can do that, however.

i'm sure this code is rife with errors but if you have some time i'd really appreciate a little help 😃

output:
[][]
[]
[]

code:

<?php
	## function declarations

$today = date("m.d.y");

function NewNews ($newstoadd) {
	$newstoadd = array ($title, $author, $today, $text);
}

function AddNews ($newstoadd, $news) {
	$news[] = $newstoadd;
}

function PrintNews ($news) {
	do {
		$i = 0;
		echo "<B> $news[0][$title] </B>";
		echo "<I> $news[0][$author] </I><BR>";
		echo "    $news[0][$today] <BR>";
		echo "    $news[0][$text]  <BR>";
		$i = i+1;
	   }
	while ($i <= count($news));

}

## main program

NewNews($newstoadd);
AddNews ($newstoadd, $news);
PrintNews ($news);
?>

form:

<FORM method="post" action="index.php">

Title
<INPUT type="text" name="title">
<BR>

Author
<INPUT type="text" name="author">
<BR>

Message<BR>
<TEXTAREA name="text" rows=30 cols=80></TEXTAREA>
<BR>

<INPUT type="submit" value="hit it!">
</form>

Try
echo "<B> {$news[0][$title]} </B>";

same for the others.

well, i tried that, when i added the curly braces there was no output.

i then realized that the first index should have been i, not 0, but it still yields no output :\

also realized the $i = 0 has to be outside the do loop.. sigh, maybe i should do this when i'm fully awake 😃

any thoughts?

Check your php.ini and see if you have error_reporting set to E_ALL....if you don't, then set it to E_ALL. It will help you learn proper programming (i.e. if you don't have it in E_ALL, you'll get used to some bad practices...)

Anyway, the reason I say that is because of this:
$i = i+1;
should be:
$i = $i+1;

and I'm surprised PHP didn't throw an error or warning...
