Kinda Java, but in PHP???

internetguy · Jan 24, 2004

Ok, I am trying to have a section on the side of my webpage with several links with friend names. I am trying to make it where when you click the link of the person's name it sends a php request to itself displaying that person, picture in the center of the page. I know everything except how to make it work by clicking links. Right now it is just the names with checkboxes. Please let me know if there is a way to do this.

Westbury · Jan 24, 2004

Make each link so that is contains a variable and value for each person. Eg

Code:

<a href=&quot;friends.php?name=bob&quot;>Bob</a>
<a href=&quot;friends.php?name=frank&quot;>Frank</a>
<a href=&quot;friends.php?name=helen&quot;>Helen</a>
.
.
.

then on your friends.php page:

Code:

switch($name)
{
case &quot;bob&quot;:
// code for putting bob info on the page
break;
case &quot;frank&quot;:
// code for putting frank info on the page
break;
case &quot;helen&quot;:
// code for putting helen info on the page
break;
default:
// code for when the user first visit the page
}

Im curious why you say this is "kinda java". Anyway, that isn't important. Hope this helps.

Oh wow thanks a lot, I only though cases related to drop down lists. And to answer your question there is a way in javascript to open another window inside the same page based on coordinates, but it sucks to write out. Anywho, thanks again.

Westbury · Jan 25, 2004

Just as a note... java is VERY different to javascript.... they are not the same thing!

internetguy · Jan 25, 2004

ok, I am having a problem, it is saying that there is no variable value for $name in the switch($name) expression. I am not sure how I am suppsoed to assign it a value without a post form.

Westbury · Jan 25, 2004

By including the "?name=whatever" after the filename it tells php to set the variable $name to the value of "whatever".
Try

Code:

switch($_GET['name'])

instead

internetguy · Jan 25, 2004

ok, now it is saying that it is an undefined index. Just for the record, I have the links of the people's names on the friends page too, I am just sendingthe request back to itself so that the picture will load in the main part of the page.

Westbury · Jan 25, 2004

I wasn't entirely sure that was going to work anyway... but I thought it was worth trying.
It shudn't matter that you are calling the same page.
Hmmm, now I clutching at straws (I self taught php to myself so I dont know everything). Try renaming the variable... I dont think "name" is a reserved word
Now your links shoud look like:

Code:

<a href=&quot;friends.php?fnam=bob&quot;>Bob</a>

and your php:

Code:

switch($fnam)
// or
switch($_GET['fnam'])

internetguy · Jan 25, 2004

Sorry buddy, it didn't work. That is pretty amazing though that you taught yourself, I have had to read from a book. I am still workin on it though, so if you think of any other ideas that would be great, thanks.

Westbury · Jan 25, 2004

hmmmm, i have this feeling its something simple. sleipnir214 might be able to see it.
Try using the age old code

Code:

if ($fnam == &quot;bob&quot;) {
// code for bob
} else if ($fnam == &quot;frank&quot;) {
// code for frank
} else if ($fnam == &quot;helen&quot;) {
.
.
.
} else {
// default screen
}

internetguy · Jan 25, 2004

Well the problem with this is that it isn't recognizing the links as variables when they are sent, so the switch function wouldn't work anyways.

Westbury · Jan 25, 2004

Ok, thats something to do with your server setup.
I *think* the setting register_argc_argv is set to off in your php.ini file.
My server configuration knowledge is very limited though

internetguy · Jan 25, 2004

Sorry, that is on too, I have global variables off though, but I doubt that would have anything to do with it.

Westbury · Jan 26, 2004

In which case (as my understanding goes) you need to use $_GET['fnam'] in your script. However, if you are using an older version of php try $HTTP_GET_VARS['fnam'] instead.

Dustman · Jan 26, 2004

Just curious.. have you tried just printing out your $_GET array to see if anything is passing? I'm not where I can test anyting right now but its worth a try..

Code:

print_r($_GET);

You might also post up your ini settings.. use phpinfo() and lets see if we can find something wrong.

Well, just glancing over it I'm not to sure why its not working. If you're sure it won't effect any other scripts running on your server, turn register globals off. Its much safer to run with them off anyways. This may clear up the problem.

Also, try running the same file that you ran with phpinfo() in it but pass it an arg.. ie phpinfo.php?name=frank

Somewhere on the page will be a list of all arguments passed into the script.. see if its making it there.

it might be useful if you post you php file code here. Maybe there is something else that is affecting it.
