Urgent help required please???

[ozzie135]

Can anyone please tell me why the below isnt working? I'm trying to create a read through the rows in a database table and create a dynamic html table (using php). The id of each row must be the id ($row['id']) of the row returned. Ive tried everything and nothing is working.

 

tried this

echo "<tr id="'<?php echo $row['id'];?>'"><td align=\"left\">";

and this

echo "<tr id="'.$row['id'].'"><td align=\"left\">";

 

and other combinations. Just seems its never getting set. No errors are being thrown, just the element id doesnt exist when I use javascript to get the element by id. If i hardcode it, it works.

 

Any help will be greatly received.

Obviously the $row['id'] is not set. We need to see more code.

The $row['id'] variable is set. I have echoed it to the page and it is correct. Im also using the id to delete the contact from the database.

 

I now feel that the id is definitely getting set, and the problem has been narrowed down to this:

 

var response = xmlHttp.responseText;
hideElement(35);

 

My hide element function simply hides the element that it is given. The above example shows that ive hard coded it to 35. This works! However, when I pass in the response variable (which definitely contains 35) it can't find the element id. How is this possible? Hard coding works, passing the variable doesn't. They both contain the same value!!!!

 

PS. I know that response definitely contains 35 as I have done the following to debug...

alert(response);

Is it set at that point in the code?

I'm not sure what that other code is....isn't it javascript? Where is the code which tells the Javascript what value to put there?

Have you looked at the source code to see what it literally sets the id to? See if it is what you want it to be.

Yeah it's an ajax response. It seems that the variable was of an incorrect type perhaps. The reason I think this is because I have changed the following:

 

var response = xmlHttp.responseText;
hideElement(resp);

 

to

 

var response = xmlHttp.responseText;
var resp = parseInt(response);
hideElement(resp);

 

This has worked and resolves the issue. It seems that the variable was being changed in the ajax call....I THINK!
