[SOLVED] Simple text area value using a variable

joesaddigh · July 21, 2009

Hi,

I am trying to make the value of a text area equal the contents of a variable and it doesnt seem to work?

echo '<textarea name="coursedescription" id="h" COLS=40 ROWS=6 value=">'.$coursedescription.'"</textarea>';

Any advice would be great

StefanRSA · July 21, 2009

No need to set the value. Just use:

echo '<textarea name="coursedescription" id="h" cols="40" rows="6">'.$coursedescription.'</textarea>';

It should work fine

joesaddigh · July 21, 2009

That works Thank you so much

I don't spose you know if there is a way of getting the text that is in that variable to be read as text and ignore the fact that is html, if that makes sense

the text in the variable is

<table width="400" border="1" cellpadding="4" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111">
                                            <tr bgcolor="#CCCCCC" class="bodygrey10"> 
                                              <td width="100%" colspan="6">  
                                                      <b>Example Timetable</b> </td>
                                            </tr>
                                            <tr bgcolor="#CCCCCC" class="bodygrey10"> 
                                              <td width="15%"> </td>
                                              <td width="17%"><strong>Monday</strong></td>

                                            </tr>
                                          </table>

Which gets read into the box fine eventually. When it first gets read in It simply shows the table with an error message

Warning: Cannot modify header information - headers already sent by (output started at E:\domains\c\cisukschool.co.uk\user\htdocs\test\Admin\editcoursesubmiteddetails.php:33) in E:\domains\c\cisukschool.co.uk\user\htdocs\test\Admin\editcoursesubmiteddetails.php on line 48

Then if you press back it will display the variable text in the text area as planned.

Any ideas how to solve this so that it will not read it as html

Thanks

StefanRSA · July 21, 2009

First things first...

To get rid of the error put

<? ob_start();?>

on the top of your form and

<? ob_flush(); ?>

right at the bottom of your form.

To display the variable on a form I would use:

<div style="width: 300px; height: 150px; overflow: auto; padding: 5px">
<? echo $coursedescription ;?></div>

Hope it helps???

joesaddigh · July 21, 2009

Im not sure if I understand what you mean or what obstart and flush do...

I have put it in various places, do you mean actually in the <form> syntax?

echo '<form ob_start(); name="editcourse" id="editcourse" method="post" action="updatecourse.php" onsubmit="return validate_form()">';

echo'</form ob_flush();>';

I know this may seem really stupid.

As for formatting the vairable with css, the variable will not always contain a table it could contain text etc...

StefanRSA · July 21, 2009

No,

Put the

<? ob_start();?>

on its own at the begining of your page before you put anything else and the

<? ob_flush(); ?>

on its own at the bottom of your page as is.

<div style="width: 300px; height: 150px; overflow: auto; padding: 5px">
<? echo $coursedescription ;?></div>

is used just to display the variable in a text box

joesaddigh · July 21, 2009

Ok I have editted the code as you said and still dont have the desired results.

The css code you gave me works fine but is not what i need. The reason being that it puts the table in the text box and not the code 'text' without executing it. Im sorry if I didnt explain myself very well. :-)

The text area code that we discussed eariler works once getting the error that I posted previously and pressing back.

My code at the moment is as follows for the wholepage.

<?php
ob_start();
session_start();
if (isset($_SESSION['user']) == false) {
	header("Location:adminlogin.php");
	exit();
	}
?>

StefanRSA · July 21, 2009

Is the form you posted the editcoursesubmiteddetails.php?

joesaddigh · July 21, 2009

No

The way that it works is a form gets posted and then runs this script which basically populates vairbales based on the chosen course title and level which is the script that the error is complaing about

<?php
session_start();

//Admin privileges 
require "../connectadmin.php";

//Get the course details which are unique together
if (isset($_POST['CourseTitle']))
{
	$coursetitle=$_POST['CourseTitle'];
}

if (isset($_POST['CourseLevel']))
{
	$courselevel=$_POST['CourseLevel'];	 
}

//Set the query
$queryeditcourse = "select * from course 
			  		WHERE CourseTitle = '".$coursetitle."'
			  		AND CourseLevel = '".$courselevel."'";
$resultcourse = mysql_query($queryeditcourse) 
	or die("Error getting course details");
$rowcourse = mysql_fetch_array($resultcourse);

//Store values in the session
echo $_SESSION['coursetitle'] = $coursetitle;
echo $_SESSION['courselevel'] = $courselevel;	
echo $_SESSION['courseprice'] = $rowcourse['CoursePrice'];
echo $_SESSION['coursefee'] = $rowcourse['CourseEnrolmentFee'];
echo $_SESSION['coursequalification'] = $rowcourse['CourseQualification'];
echo $_SESSION['courseactive'] = $rowcourse['CourseActive'];	
echo $_SESSION['coursedescription'] = $rowcourse['CourseDescription'];	


//Get the course id, perform seperate query, Save id in session variable
$queryeditcourse = "select CourseId from course 
			  		WHERE CourseTitle = '".$coursetitle."'
			  		AND CourseLevel = '".$courselevel."'";
$resultcourse = mysql_query($queryeditcourse) 
	or die("Error getting course details");
$rowcourse = mysql_fetch_assoc($resultcourse);
$courseid = $rowcourse['CourseId']; 

$_SESSION['courseid'] = $courseid;

//Return user to course page
header("Location: editcourseform.php");
exit();
?>

It seems to be complaining about the header("Location..............) bit of code??

joesaddigh · July 21, 2009

Right sorted I needed to put the start/flush code on that script#

Thank you so much all working perfectly!! Sorry for being so clueless!
