Passing from Javascript to PHP

Javascript & Ajax
#1

I have a php generated webpage that reads in data from a MySQL database and displays it. One of the database fields being displayed can be moused over and it creates a link. (this is adapted code so I can’t say it ever worked).

In the beginning of the code is this:

[php]
[/php]

Later in the code, is this (this generates the link based on the mouse-over)

[php]print "


<a href=“javascript:smallpopUp(‘sendcmd.php?cmd=$prefix$row[code]’)”>
$row[code]

";[/php]

What is supposed to happen is that when any displayed entry is clicked, the script sendcmd.php is supposed to be called (this part works) and the value of $cmd passed to it. Of course $cmd is empty at the popup window (sendcmd.php).

What do I need to do in order to make this work?[/code]

#2

No one, eh?

#3

What does your HTML output look like? (Not the PHP print, the actual output)

#4

HTML is fine - fields are displayed correctly. While this is a lot, here’s the page source

Simple testing…

var_dump($_GET);

Using “cmd=1”

array (size=1)
  'cmd' => string '1' (length=1)

Using “cmd=#1”

array (size=1)
  'cmd' => string '' (length=0)

So… remove the # it is for anchors not the query string.

#6

Sorry, I’m kinda new to this.

Do you want me to create a new php file with your code and run it?

#7

No, I’m saying you need to remove the # symbol from your query string.

[php][/php]

#8

Man, I wish there was an edit feature here! ;D

Anyway… the $prefix variable was adding the # so I removed it. Now it shows in source (for example)

[php]

Alarm 3 Interogate


3913[/php]

Still doesn’t pass to sendcmd.php though…

#9

What is the code in sendcmd.php?

#10

Ok… it appears to now be working! Thanks for your help
