ok this is the strangest thing ive ever seen....

this following code works....

<?php $about me = "text<br />text"; ?>
<?php $about_me = str_replace('<br />', '<br>', $about_me); ?>
<script type="text/javascript">
function toggle_visibility(id)
{	
var div = document.getElementById(id);	
var text = document.getElementById("about_me_text");		

if(div.style.display == 'none' ) 
	{		
	div.style.display = 'block';		
	text.innerHTML = "<?php $about_me = str_replace('<br>', '\n', $about_me); ?><?php echo $about_error; ?><form action='' method='POST'><textarea cols='23' rows='6' name='textarea_about' id='textarea_about' style='font-family:arial;font-size:13px;overflow:hidden'><?php echo "$about_me";?></textarea><br><input type='submit' name='submit_about' value='Save'>   <input type='button' name='cancel_about' value='Cancel' onClick=\"window.location.href='content.php?content=myhub&myhub=mypage&mypage=mypage&cont=<?php echo $cont;?>'\"></form>";	
	}	
	else 
	{		
	div.style.display = 'none';
	text.innerHTML = "<?php $about_me = str_replace('\n', '<br />', $about_me); ?><?php echo $nothing.$about_me; ?>";
	}
}
</script>

but this does not work....

<?php
$about_me_query = mysql_query("SELECT * FROM page_set_data WHERE username='$username'");

while ($row = mysql_fetch_assoc($about_me_query))
{
$about_me = $row['about_me'];
}

if (!$about_me)
{
$about_me = "";
$nothing = "Write about yourself";
}
?>

<?php $about_me = str_replace('<br />', '<br>', $about_me); ?>
<script type="text/javascript">
function toggle_visibility(id)
{	
var div = document.getElementById(id);	
var text = document.getElementById("about_me_text");		

if(div.style.display == 'none' ) 
	{		
	div.style.display = 'block';		
	text.innerHTML = "<?php $about_me = str_replace('<br>', '\n', $about_me); ?><?php echo $about_error; ?><form action='' method='POST'><textarea cols='23' rows='6' name='textarea_about' id='textarea_about' style='font-family:arial;font-size:13px;overflow:hidden'><?php echo "$about_me";?></textarea><br><input type='submit' name='submit_about' value='Save'>   <input type='button' name='cancel_about' value='Cancel' onClick=\"window.location.href='content.php?content=myhub&myhub=mypage&mypage=mypage&cont=<?php echo $cont;?>'\"></form>";	
	}	
	else 
	{		
	div.style.display = 'none';
	text.innerHTML = "<?php $about_me = str_replace('\n', '<br />', $about_me); ?><?php echo $nothing.$about_me; ?>";
	}
}
</script>

and the data in the database is exactly the same, i have also connected to the db further up in the page..

The code below is supposed to put the variable $about_me in a textarea by using javascript but i have to change " " to "\n" when it goes into the textarea tags i am getting my logic all wrong trying to do this, and i think i have things in the wrong places.

A user posts some data into the database using <textarea>, but if there is a line break in the data that they enter, it uses this " " how can i stop it from posting " " and get it to post " " instead. Thanks

January 22, 2010

Thanks nightslyr, you've saved me alot of time

January 22, 2010

if each user uploads there own image then you could concatinate there userid with there file name as each userid will be unique

January 21, 2010

slight change of plan.....

please visit this link and explain why the user has to click "edit" twise before the text changes, if i can resolve this, i believe i could solve my problem above.

Whenever the variable name "$about_me" has any tags in it, the following like does not work...

<a href='#' onclick="toggle_visibility('about_me_popup');"><font color='CornflowerBlue'>Edit</font></a>

What am i doing wrong? Thanks

January 21, 2010

sorry guy, ive just done it AT LAST!

January 21, 2010

I have some data in a database (about_me). When there is no data in "about_me", everything works fine and the user can upload data but when data is put in by the user, and the user then wants to edit it again, it doesnt work.

This is the php to upload the data

<!-- about me upload -->
<?php
if (isset($_POST['submit_about']))
{
if (isset($_POST['textarea_about']))
{
$textarea_about = nl2br($_POST['textarea_about']);

	if (strlen($textarea_about) < 301)
	{
		mysql_query("UPDATE page_set_data SET about_me='$textarea_about' WHERE username='$username'");
		header("location:http://www.squiblo.com/content.php?content=myhub&myhub=mypage&mypage=mypage&cont=$cont");

	}
	else
	$about_error = "<ul><li>About you have as maximum of 300 characters.</li></ul>";

}

}
?>

This gets the data from the database and puts it into variable

<?php
$about_me_query = mysql_query("SELECT * FROM page_set_data WHERE username='$username'");

while ($row = mysql_fetch_assoc($about_me_query))
{
$about_me = nl2br($row['about_me']);
}

if (!$about_me)
{
$about_me = "Write about yourself";
}
?>

This is the javascript to change from showing the data in textarea or not

<script type="text/javascript">
function toggle_visibility(id)
{	
var div = document.getElementById(id);	
var text = document.getElementById("about_me_text");		

if(div.style.display == 'block' ) 
	{		
	div.style.display = 'none';		
	text.innerHTML = "<?php echo $about_me; ?>";

	}	
	else 
	{		
	div.style.display = 'block';		
	text.innerHTML = "<?php echo $about_error; ?><form action='' method='POST'><textarea cols='23' rows='6' name='textarea_about' id='textarea_about' style='font-family:arial;font-size:13px;overflow:hidden'><?php echo nl2br($about_me);?></textarea><br><input type='submit' name='submit_about' value='Save'>   <input type='button' name='cancel_about' value='Cancel' onClick=\"window.location.href='content.php?content=myhub&myhub=mypage&mypage=mypage&cont=<?php echo $cont; ?>'\"></form>";	
	}
}
</script>

And finaly here is some HTML

<div id='about_me_text'>

	<?php echo $about_me; ?>
	</div>

	<div id='about_me_popup' style="display:none">

	</div>

If you are finding it hard to understand me, please say so and ill link you to the page. Or i you know how to do this and please could you show me a better way for doing this. thanks

Thank you everyone!

The following function only works for the variable "$forname" how can i get it to also work for $surname and $city

function validCharacters($input)
   {
      //Returns true if all the characters are letters (upper and lower case)
      return (preg_match("/[^\w]/", $input)==0);
   }

   //Usage
   if (!validCharacters($forname)+($surname)+($city))
    {
      echo "All boxes can only contain letters";
    }
      else
   {
      echo "success";
   }

January 19, 2010

what exactly will that function do, because i need an else saying something like, "You can only use letters"

January 19, 2010

If a user enters data into an input field, i do not want them to be able to upload special characreters like the following or numbers:

"- #'][{}£$%^&*()â▀♣

and many more from character map.

how can i do this, by checking a variable like...

$username = $_POST['username'];

Thanks.

January 19, 2010

Even though the input fields do not have any spaces in them, my if statement below always echoes "No boxes allow spaces". I was wondering if i have set up the if statement correctly, thanks.

<?php
if ((substr_count($forname, ' '))&&(substr_count($surname, ' '))&&(substr_count($city, ' ')) < 1)
   {
     echo "success";
   }
     else
     echo "No boxes allow spaces";
?>

an easier way of putting it, how can i merge these 2 queries into 1...

mysql_query("SELECT * FROM table WHERE user_id='$user_id' AND friend=1");

and

mysql_query("SELECT * FROM table WHERE other_person_id='$user_id' AND friend=1");

and then my aim is to echo out the the row that doesnt have $user_id in it

NOTE: $user_id will never been the same in both rows

January 13, 2010

Thank, but i also what to select all from where other_person_id = '$user_id'

January 13, 2010

You mean something like this?

<?php
$query = mysql_query("SELECT * FROM date_table");

while ($row = mysql_fetch_assoc($query))
{
$day = $row['day'];
$month = $row['month'];
            $year = $row['year'];
}

echo $day ."/". $month ."/". $year ."<br />".;
?>

January 12, 2010

forget that previous post, thats just be being stupid once again...i think i ment this...

mysql_query("SELECT * FROM table_name WHERE user_id='$user_id' OR page_zebra_id='$user_id' AND friend=1");

i have tried this but it only give me data from 1 row

January 12, 2010

i came up with this, but im not sure...

SELECT * FROM user_id AND page_zebra WHERE user_id='$user_id' AND page_zebra='$user_id'
