I'm relatively new to this and am familiar with echo in PHP but what I need is to have the contents of a field in a database to be placed in the page (but not as a written field)
For example
<?php echo $product_description['description']; ?>
the field description has html formating in it already so when I use 'echo' it writes out for example
<p>text on firstline <br> text on next line
And what I want is that this html from this field in the database that already has html formating to simply placed in the php page which would make it look like this
text on firstline text on next line
I assume I just need to use a different command than ECHO but don't know which one.
Try
echo html_entity_decode($product_description["description"]);
If that works, the HTML in your database has been encoded using htmlentities, so you must decode it to write to a page.
strip_tags is what you're after.
Use it like so: echo strip_tags($your database bit to echo here);

I have this textarea called personalInfos where i fill the infos in following format :
<p><span class="white">1966 - '69</span><br/> text .... </p>
When i submit it to database, it gets saved ok, same format. When i retrieve the code from database to admin textarea it gets filled ok.
My only problem is on front end where i get displayed the code as text not rendered as html code. So basiclly i see it on the page like this :
<p><span class="white">1966 - '69</span><br/>
Most likely you display fetched code parsed processed by htmlentities() or similar function. This is in most cases the way to go to avoid planting i.e. html in comments. So simply stop doing this after fetching (or insert - depends where you do so) and your content will be outputed as literaly HTML and properly processed by web browser.
You should have a look at htmlspecialchars_decode()
Example
$str = '<p><span class="white">1966 - \'69</span><br/> text .... </p>';
echo htmlspecialchars_decode($str);
Also make sure to escape the single quotes as well.
One of the fields in our PHP page is a description - occasionally there are website links included. However, when pulling this data from the database table the links remain non-clickable. How can I parse text from database table as HTML in final rendered PHP page? Thanks!
Do you mean something like this?
<?php
echo "<a href='$linkLocation'>$linkName</a>";
?>
[Edit]
Server-side you could transform the orginal text ($det[9]) like this (based on this SO question):
<div id="text"><?php
echo preg_replace_callback(
'/http:\/\/([,\%\w.\-_\/\?\=\+\&\~\#\$]+)/',
create_function(
'$matches',
'return \'\'. $matches[1] .\'\';'
),
$det[9]
);
?></div>
[Edit: merged the original code from your comment]
[Edit: fixed typo]
Are your text stored as HTML or is it just a text containing URLs?
Follow these steps
Change the db feild to text,
While inserting data convert the html entities and escape the quotes.
while retrieving do the reverse process and you can retrieve data in html format this way
I'm getting data from my textarea with the following code
$about_me=mysql_real_escape_string(nl2br($_POST['about_me']));
which
1. Receives data, using $_POST.
2. nl2br makes brakes so If I echo this code to user he will see if there were new lines.
3. mysql_real_escape_string to secure code from mysql injections before entering it to database.
So if I echo this code everything works fine.
But If I edit it again through textarea, php goes to mysql gets data, puts it to textarea and I see <br> signs...
How can I get rid of them while editing my text again in textarea ?

Stop using nl2br(), of course. It's entirely wrong here.
You use nl2br() when you want to output data that contains linebreaks to HTML, not when you want to store it in the database. Store data unchanged, format it for viewing.
If you output it into a <textarea> you don't need to use it either, since textareas display linebreaks (whereas HTML in general does not). For the textarea you need htmlspecialchars(), but apparently this is already happening - otherwise you would not see literal <br> showing up.
<?php
function br2nl($string){
$return=eregi_replace('<br[[:space:]]*/?'.
'[[:space:]]*>',chr(13).chr(10),$string);
return $return;
}
?>
Use this while getting data from database and before printing into textarea .

I have some multi line text saved in MySql database (VARCHAR 255). When i load it, and process it using standard php function "nl2br", it echoes fine (multi line). But, when i load multi line text from database, make it "nl2br" and then send it to javascript (so it gets displayed in textarea), it won't be displayed! What's wrong?
echo "<SCRIPT>FillElements('".$subject."','".$text."');</SCRIPT>";
P.S.
FillElements function:
function FillElements(Sub,Txt)
{
document.getElementById('txtSubject').value=Sub;
document.getElementById('txtMessage').value=Txt;
}
textareas don't actually store the contents in an attribute like value in the same manner as input elements. They actually store the contents in in between the <textarea> and </textarea> tags. Meaning that the contents is actually treated as CDATA in the document.
<textarea>
This is my Content
</textarea>
Produces a text area with "This is my Content" as the contents.
The implication of this is that you cannot use the code you have to alter the contents of a textarea. You have to alter the innerHTML property of the textarea. I have set up a simple example here:
http://jsfiddle.net/wFZWQ/
As an aside, since you are populating the fields using PHP on the creation of the page, why not merely fill the data in the HTML markup, this seems like a long way round to do it.
Also, since you don't appear to be using it, have you seen [jQuery][1] it abstracts alot of things out, so instead of typing document.getElementById("the_id") to get an element you can use CSS selectors and merely write $("#the_id") to get the same element. You also get a load of useful functions that make writing javascript mucxh easier.

Newline tags (<br />) don't cause actual new lines in <textarea>.
You can pass the "real" newlines (\n) to your <textarea>, though.
I created a fiddle for that.
EDIT: For the updated FillElements code:
$subject = "String\nWith\nMultiple\nLines";
printf('<script type="text/javascript">FillElements(%s)</script>',
json_encode($subject)
);
My guess is that your HTML source code looks like this:
<script>FillElements("foo","foo
bar
baz");<script>
Correct?
In JavaScript, strings cannot span multiple lines...
so I need the user to write a review about an article or book and send it to a DB via PHP but with some basic HTML formatting.. I mean, I have a form , when the user writes the review, the data is sent but without any kind of formatting, If the user want to write in a new line, the text is sent like plain text, I need to get also those new line breaks and simple stuff.
I know how to use PHP and DB connection, I just need to know how to get those new line breakes and stuff..
Use nl2br
Just before printing on the screen data from DB. It replaces \n (new line) as <br>
I recommend storing the data as plaintext, and adding the formatting on the way out. This way if you want to change the way it is formatted then you don't have to update every row in the database.
you can use nl2br() if you just need to newlines to be formatted, and a search-and-replace for anything else.
Have you considered using an existing 'plain text to markup' solution, like Markdown?
It (and others like it) allow your users to write plaintext reviews that will be sensibly formatted. (like stackoverflow uses!)
The PHP function nl2br() basically takes every new line your user enters via the form and converts the new line code to a <br> tag.
An example of using this would be:
$text = nl2br("This is text \nThis is a new line of text");
This would create the following code in your database:
This is text<br>This is a new line of text
When the user hits enter in the form textarea, PHP will pick this up as \n.
