Confusing problem

[Yuki]

To see the site I'll be referring to,To see the site I'll be referring to, please goto http://shahinrostami.com/webdevass2/login.php

Username: admin

Passsword: istrator

 

 

Basically, navigate to a Question within a module, you'll see a form at the bottom for adding questions.

 

when you click that, I need to be able to echo out either the MySQL error or "New Question Added"

 

so I have:

 

mysql_query($query) or die('Error, insert query failed');

 

echo = "New question added";

 

 

 

 

admin.php contains the div I want to be using to print out notifications like that, it's the

 

<?php

    echo "<div class=\"notification\">";

    echo $notification;

    echo "</div>";

    ?>

 

problem is it's above the case switches that include the body.

 

I don't understand how to get round this purely using PHP, help please!

Instead of echoing it there, assign it to a variable.  Then below, in the appropriate location, echo out that variable.

[Yuki]

no you see that's the problem, it needs to be echo'd in a div above the div where it can be assigned, have alook at the source, I've already tried what you suggested

[Yuki]

Most my code is procedural, the only thing that I've made my own function for is when I have to re-use the EXACT same code twice.

 

 

The part that needs to print out the message is the parent, I consider the include the child (conceptually in this scenario)

 

 

 

$notification;

echo $notification;

 

 

// question.php has a form in it that inserts questions into the db

include "question.php";

 

 

 

 

now, I want $notification to print out the mysql error message. Problem is, it's echo'd before the include, if it was after, all would be fine, I could do it like the previous poster stated, cast it into a variable, and print it out.

 

[Yuki]

any ideas?

[Jeremysr]

Why can't you echo it inside the question.php file?

[Yuki]

because the site layout isn't like that, check the link, it needs to be echo'd out inside the red thin box

[Yuki]

is nothing possible then?

[p2grace]

Either you need to rethink the logic behind the system, or you need to use javascript/ajax (your preference) to update the div with the correct content.

[Yuki]

It's going to have to be AJAX/Javascript. Was trying to avoid learning any of that until this project is over, I understand the concepts though, anyone have any links to tutorials/manuals with simple explenations of something as simple as I'm trying to do?

 

ONE div on the page that needs to have something echo'd out to it AFTER it's displayed

[p2grace]

If you have the id of the div you could use this in your php script.

 

Javascript Example:

 

<?php
// the code you want to echo
$echo = "this is the html code";
// script to display it
echo "<script type='text/javascript'>document.getElementById('id_of_div').innerHTML = '".$echo."';</script>";
?>

[Yuki]

I'll try that when I get back to work, looks very simple and I can understand it! Hope it works fine, thank you very much.

[Yuki]

Cool it works, now I just need a way of hiding the DIV whe there's no text output to it, any ideas?

 

 

Help!

[p2grace]

By default have it shown to display none.  Then change the display to block with javascript.

[Yuki]

Makes sense but I can't seem to get my head round it. The Stylesheet is included, .css file

 

.notification{

background-color: #DB4105;

color: #FFF8E3;

width: 60%;

display: none;

}

 

 

 

I've added display: none;

 

what would I pass through using javascript

[p2grace]

Don't add display none to the css stylesheet, hard-code it into the div.  Here's how it should work.

 

<!-- FOR THE DIV -->
<div id="div_id" style="display: none;"></div>
<?php
// the code you want to echo
$echo = "this is the html code";
// script to display it
echo "<script type='text/javascript'>
var divid = document.getElementById('div_id');
divid.style.display = 'block';
divid.innerHTML = '".$echo."';
</script>";
?>

 

I believe that should work.  I didn't test it.

[Yuki]

Hey I tested it, it doesn't work, doesn't display the box

[p2grace]

Hmm try this instead:

 

<!-- FOR THE DIV -->
<div id="div_id" style="display: hidden;"></div>
<?php
// the code you want to echo
$echo = "this is the html code";
// script to display it
echo "<script type='text/javascript'>
var divid = document.getElementById('div_id');
divid.style.visibility = 'visible';
divid.innerHTML = '".$echo."';
</script>";
?>

 

See if that works.

[Yuki]

display: hidden

 

doesn't hidethe div, it's still visible.. 

[p2grace]

sorry, it's supposed to be visibility: hidden.

[Yuki]

Hey, I managed to get it working with the original code you gave me and http://www.devpapers.com/article/72

 

thak you
