Passing Variables through <tr onClick>

sanju

I am trying to pass a few variables on a click of a table row between two PHP files, say from Page1 to Page2. The Page2 opens in a IFRAME window on Page1 itself. This is how I am passing my variables.

<table>
<tr ... ... onClick="Page2.php?var1=$var1&var2=$var2" .... "IFRAME <NAME>.....>
...
...
...

This is what I am doing:

😃 In Page1, I have a function myFunc which draws the above said <table>
😃 Inside myFunc, after the <tr......> I am declaring and assigning values to var1 and var2
😃 var1 and var2 are declared global

This is what happens:

🆒 The Page1 draws my <table>
🆒 The default IFRAME opens in Page1 with my pic. 🆒
🆒 On a click of a row, the Page2 opens in my IFRAME window.

These are my Problems:

😕 The values are not being passed to Page2.
😕 And a little confused over the behaviour of onClick.

To make the long story short, :mad:

Lets assume that I have a Calendar of Sept. 2002 displayed on a <table> in Page1, each row in that <table> represents a week from Sun to Sat. Now upon clicking a row from that <table>, I want to pass the start and end dates to my Page2.

Note: I am a newbie to PHP and trying this stuff out, any help would be appreciated.

code and can fire a javascript function on a page. the onclick by itself can't redirect to another page...

you need to write a js function to submit some variables to the server and get it to do what you want...or pass them back to another open window...

Are you sure about that. I am using something like,

onClick="frames['frame1'].location.href='www.yahoo.com'">

and it seems to work fine, provided my IFRAME being named "frame1".

Depending on your version of PHP, you may have to access your variables like this ...

$_GET["var1"]

I dont think I have a problem Getting the values, the problem is where I assign them.

You see, this is the code I have in my <tr> and IFRAME.

:: <tr> Segment in function xyz() in mainFile.php

function xyz()
{
global $fday, $lday;

for(....)
{

<tr onMouseover="this.bgColor='#9999FF'"
onMouseout="this.bgColor='#000000'"
onClick="frames['internal'].location.href='test.php?
fday=$fday&lday=$lday'">

        for(....)
           {
              ...  <td> // first day of week      
              $fday = here is where I assign the value
              ...
              ...
              ...
              ... <td> // last day of week
              $lday = here is where I assign the value
              ...
           }
           </tr>
         }

}

:: IFRAME Segment in mainFile.php

Note: I am not passing the values in IFRAME initial load.
[/COLOR]
[/SIZE]

I have also initially tested the mainFile.php page to display all the results I want in the same page. So, the variables does hold the value upon opening the page. But it is somehow not able to retain it to send it to test.php, when the onClick in <tr> has been triggered. Any ideas ?

Your PHP variables are not accessible unless you actually go into PHP to get them. This line ...

should look like this ...

Theeper,

I think I have confused you too 🙁. All of my code is inside php, I was just too lazy to type all that up, since I have the source sitting at my home computer. So, that <tr> I was talking about, it is actually inside an echo();
