PHP Tooltip (nearly there..)

Hi everyone I hope i find you all well.
Firstly, A HUGE THANK YOU to you AWESOMELY KIND PATIENT GURUS on here (you know who you are :>)) who helped me with this question on a previous post. This is a cut down non-spaghetti version of that, which i could not yet get working (most probably due to me being a bit 'slow', and not because of the skillful people who tried to help me on this). I think this time we will have better luck as Ive made some progress now (which is predominantly due to the ever-helpful brilliant minds on here :>))

I have a function guys that displays tooltips.
The function is named:    wz_tooltip_image
I call it by: wz_tooltip_image ($displaynamelink, $title)
I am calling this inside a WHILE LOOP, in order to display images from records in a mysql table.
So a call might look like below:

while ($row = mysql_fetch_object($rs)) {      
wz_tooltip_image($row->name_ent, $row->name_ent);
}
      
The problem I am having with this function is with the $stuffimage variable.

-----------------------------------------------------------------------------------
WHAT DOES WORK IN THE $stuffimage variable:
-----------------------------------------------------------------------------------
In the following, I have just placed part of $stuffimage (the important parts):

1) Sending a variable through a query string to image_fetcher.php: THIS WORKS
onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=102\'>',

2) Hard coding the image name: THIS WORKS
onmouseover=\"Tip('<img src=\'cat.jpg\'>',

-----------------------------------------------------------------------------------
WHAT DOES NOT WORK BUT WHAT I NEED TO GET WORKING
-----------------------------------------------------------------------------------
Although the above 2 points work, I dont want to use these methods
in reality, since Im hard coding either the GET variable, or the image
I want to pull the image records from a mysql table, so I need to get point 1 above, which is:

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=102\'>',

which DOES WORK, to be slightly changed to push the $row->id_ent to image_fetcher.php

THE BELOW DOES NOT WORK, and errors with 'Unterminated string constant'
THIS IS THE ONLY PART I NEED TO GET WORKING.
onmouseover=\"Tip('<img src=\"imagefetcher.php?id_ent='.$row->id_ent.\'>',

The problem above is with how i am escaping the
?id_ent='.$row->id_ent

Any help on this I would be truly grateful.

Thank you everyone :>)

The wz library is now very old. You should take a look at more modern replacements like http://livepipe.net/control/window

This syntax should work fine (it's something you have tried above already) - it tested ok for me. The only problem I can see is that line breaks inside $wz_tooltip_config_image will probably break Internet Explorer as it doesn't handle white space properly.

$stuffimage = "<a href=\"#\" $style onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=$row->id_ent\'>',$wz_tooltip_config_image)\" onmouseout=\"UnTip()\">$displaynamelink</a>";

Check that you don't have a line break in the middle of $row->id_ent

This works:

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=102\'>'

but this doesnt:

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=$row->id_ent\'>'

Try:

var_dump($row->id_ent);

To confirm what is in that var.

That looks ok. Weird that it works for me. You could give this a go:

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent={$row->id_ent}\'>'

or drop out of interpolation and concat it yourself:

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=".$row->id_ent."\'>'

Squinky, i wonder if it could be the following..

The function im defining has $stuffimage inside of it.

Im calling the function INSIDE a WHILE LOOP,  as follows:

while ($row = mysql_fetch_object($rs)) {      

wz_tooltip_image($row->name_ent, $row->name_ent);      


So im wondering if that is why $row->id_ent

is not being seen in the query string, because:

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=$row->id_ent\'>'

is defined in the function?

What i get is:

http://localhost/dropdowndbpilot/pagination/paginationpilotdb/image_fetcher.php?id_ent=

when using:

$stuffimage = "<a href=\"#\" $style onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=$row->id_ent\'>',$wz_tooltip_config_image)\" onmouseout=\"UnTip()\">$displaynamelink</a>";

and the above is INSIDE the function, OUTSIDE the WHILE statement.

But, in the WHILE statement, i can do

var_dump($row->id_ent);      

and get the id_ent value.

<<<<<<<<<<<<<<<<< MATE IT WORKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! >>>>>>>>>>>>>>>>>>>>>>

It was because my definition of $row->id_ent was INSIDE THE FUNCTION.

I changed the function to include a 3rd parameter as follows:

function wz_tooltip_image ($displaynamelink, $title, $showme) {

blah blah

onmouseover=\"Tip('<img src=\'image_fetcher.php?id_ent=$showme\'>',

}

then called it with:

wz_tooltip_image($row->name_ent, $row->name_ent, $row->id_ent);      

and it works!!!!!!!!!!!!!!!


MATE THANK YOU SO MUCH FOR YOUR KIND HELP!!

Well if $stuffimage is defined inside the function, it won't exist outside it. Similarly, if $row is defined outside the function then it won't be available inside it. Are you echoing $stuffimage inside or outside the function?
