PHP_Self

Ack! What is wrong with this?
echo '<form method="POST" action="<$PHP_SELF?isdelete=$delete>">';

I get page not found.

why do you have carrots surrounding your action? You should view your source once the form isl oaded up in your browser and see how the html is outputted. Anyways, try this

echo '<form method="post" action="$PHP_SELF?isdelete=$delete">';

Thanks cgraz. Unfortunately, that didn't work either. I still get page not found.

cgraz

You get a page not found error after submitting the form? Can you post a link?

Yes. I'm trying to create an admin page to update the database records. I want to pass parameters and have it come back to the same page so I can delete the record.

I also tried this:

echo '<form method="post" action="$_SERVER['PHP_SELF']?">';
echo '<p><input type="submit" value="Delete Item" name="delete">

Did you ever look at the actual source code like I suggested after the PHP has been parsed. That will pretty much solve your problem. You'll be able to see what PHP Is doing.

You can try this though

<?

// php code here

?>

<form method="post" action="<?=$PHP_SELF?>?isdelete=<?=$delete?>">

<?

// more php code here

?>

I did look at the source code; I'm new at this and I apologize for being stupid, but I couldn't figure out why it wasn't working.

I did find something that does work:

echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';

Now, I have to figure out how to get the parameters in there and I'm all set!

Thanks for being so patient!

Just out of curiosity, do you know WHY the others you tried didn't work? If you don't, ask, and we can explain it to you! 🙂

I'd love to know why the others didn't work! I feel so stupid!

Don't feel stupid, it's all part of learning 🙂

echo '<form method="POST" action="<$PHP_SELF?isdelete=$delete>">';

There could be 2 reasons this one didn't. The main one is the < >'s around the variable. Assuming register_globals is turned on, that would have sent the form to the page: <self.php?isdelete=deletevalue>

The second reason is as I stated above, register globals. If register_globals is turned off (default), you have to refer to your passed variables via their reserved names. For posted forms, $POST['varname'], for server info, $SERVER['PHP_SELF'], for URL variables (get method), $_GET['varname'], etc.

echo '<form method="post" action="$_SERVER['PHP_SELF']?">';

That one didn't work because of the single quotes. Single quotes will output exactly what is inside of them. In the case of variables, it will just output the name of the variable, rather than the value.

Personally, I would have done it like this:

echo "\n<form method=\"post\" action=\"".$_SERVER['PHP_SELF']."\">";

Granted, it does look a bit more confusing, but I find it easier when I'm debugging. The \n will put a new line in your html, so you can indent your html code, make it easier to read. The \" escape the " so that it doesn't close the echo construct before you want it to 🙂

Hope that helps,
Matt

That does make it easier to debug - thanks so much for taking the time to explain!!
