Edit/Delete via form

cyronuts

Greetings,

I've made a form, with two submit buttons - one for editing, the other for deleting the current drop down selection:

Then,

I've got code like so in the processing script to test, and it ain't workin:

require_once("sc_fns.php");

admin_header();

if( $_POST['cmd'] == "edit_category" ) {
echo "good";
}

else if($cmd == "delete_category") {
echo "delete";
}

ANY CLUES WHY, thanks! I tried w/wo the $_POST, but no dice.

o yes, i 4got there was meant to be a space in else if, silly me

if( $HTTP_POST_VARS['cmd'] == 'edit_category' ) { 
echo 'good'; 
} 

elseif($HTTP_POST_VARS['cmd'] == 'delete_category') { 
echo 'delete'; 
}

im going to assume you made the form use the post method,

why didnt you go to ANY php tutorial or php.net and read the first page. God its hardly difficult.

ok first off dont pay any attention to the rude folks on the board, they'll get theirs...now onto your prob

mind you im pretty new, but as I understand it the submit button will (lets assume your using post as your method) post all variables on the form to the page you are submitting to...in doing this you are submitting also the second button in which case you are assigning dual values to cmd and making it an array like $cmd['cmd'].

what I would do is instead have two radio buttons. one for each option assign something like $cmd['edit'] value = true for each option then use and if (isset $cmd['edit'] ) to fork the process.

anyway hope this helps

Mega,

A) No need to bring the Lord into this.

😎 Yes, I've read tutorials, but isn't the point of a forum so that veterans can help newbies, and possibly newbies help veterans? I realize it is a simple question, but what is simple to you, ain't so simple to someone new at this.

C) I've entered the code exactly as you had, and guess what - it still returns a blank page. Any ideas, vet?

Here is my form submit buttons:

Here is the script processing code, which still returns a blank browser:

require_once("sc_fns.php");

if( $HTTP_POST_VARS['cmd'] == 'edit_category' ) {
echo 'good';
}

elseif( $HTTP_POST_VARS['cmd'] == 'delete_category' ) {
echo 'delete';
}

Thank you Kenderized, I'm not sure I understand, but let me try and digest that.

Kenderized...

Just shooting in the dark here...but can't I use images instead of radio buttons?

Do you have any snippets I can peak at, this has me totally confused.

At the top of your form page you do have a line that reads

the variables will only be avaiable on the page you post to.

or even better use Session Variables instead they will be available everywhere for as long as you have a session

also you can use $_Post, instead save yourself the carpel tunnel

hey,

don't mean to sound like a complete programming illiterate moron, BUT:

yes, I've got the post command in the form, I guess I am having trouble with the concept of

1) what should the two values be named?

2) where in this code do I use those names and the isset function...

require_once("sc_fns.php");

if( $HTTP_POST_VARS['cmd'] == 'true' ) {
echo 'good';
}

elseif( $HTTP_POST_VARS['cmd'] == 'delete_category' ) {
echo 'delete';
}

Try this in your HTML:

<form action=script.php method=post>
<input type=hidden name=action value=edit>
<input type=image src="edit.gif" value=submit>
</form>

<form action=script.php method=post>
<input type=hidden name=action value=delete>
<input type=image src="delete.gif" value=submit>
</form>

and in your PHP:

if ($action == "edit") {
   do something;
} else if ($action == "delete") {
   do something else;
}

Hope this helps.

Alternately, you could do:

<a href="script.php?action=edit"><img src="edit.jpg" border=0></a>
<a href="script.php?action=delete"><img src="delete.jpg" border=0></a>

I prefer the previous method, as it doesn't append the $action variable to the URL...

Sorry just, you never know how much code someone has done when speaking to them for the first time...any who ok how about something like this (I always say get it to work tweak it later) so lets just get it to work.

if ( $_Post ['cmd']['Edit'] == "true")

[
echo "good"
]
if ( $_Post['cmd']['delcat'] == "true")

[
echo "bad"
]

this is kind of stripped down version of what you want I scrapped the idea of isset you could do it that way but this is easier for now I have to run so I wont be on in 20min, but good luck
