Update query with nl2br and preg_replace, something funny happening


Recommended Posts

So what I have is a Rich Text editor I made myself it all works great except when I submit the form. My assumption is that it has to do with either nl2br or preg_replace. I have made my own bbcode converter thingy lol.


anyways... after click submit and it updates the database fine, but it will put in a lot of <div> elements in the string and I don't have it set to put in <div>'s anywhere except for justify text left,right,center or full. so heres the code thats involved with this.



    if (isset($_POST['submit'])) {
	include 'bbcode.php';
	$content = $_POST['hiddenpost'];
	$content = nl2br($content);
	$content = preg_replace($pattern, $replace, $content);
	mysqli_query($con, "UPDATE news SET content='$content' WHERE id='1'") or die("Update Error: ".mysqli_error($con));
	echo 'Page has been Updated. Thank You <br /><br />'.$content;  // the $content is just there for testing purposes
    $result = mysqli_query($con,"SELECT * FROM news")
	or die('Result error: '. mysqli_error($con));
    while($row = mysqli_fetch_array($result))
	    $date = date('D M j, Y',strtotime($date));
    <div class="c_header"><div id="pad_content"><input name="header" value="<?php echo $header; ?>" /></div></div>
    <div class="c_content"><div id="pad_content">
    <div class='gre-toolbar' id='toolbar-gre'>
        <select id="size" onchange="select();">

I would try adding one bbcode at a time, until the divisions started showing up.  I think you will find it a nesting problem, but I cannot spot it right off hand.


I actually removed my preg_replace for the bbcode and it still gives me these magical divs haha, now to look farther in what the heck is happening.. grrr


Going through your code and debugging it is your responsibility unless you want to hire a consultant


edit : lol

lol, well I was just hoping it was just a minor thing i missed, but apperently its not. how could this be debugged when its working, just adding divs on every new line... like it will wrap a <br> in a div haha

have you even pined down at what point the data contains the <div> tags? is in present in the $_POST'ed data, in the query statement, when you retrieve and display the data?

it is in the $_POST data, which is sent to the mysql db and shows the <div>'s in the database. using textarea instead of <div editable="true"> seems to not have the magical divs when submited but then my custom bbcode buttons dont send to the textarea... 


im going to do some more research on sending content from div to hidden textarea without jquery and see if it is jquery that is messing my code up. ive downloaded jquery 1.10.2 uncompressed to see if there was some stuff in there that is creating divs... which there seems to be a few in there about it. but im not the best with jquery thats why i dont use it to often.

i made an additional post while you were writing your reply above. is your code using a jquery .html(); method to get the content for submission? if so, try the .text() method.



yes i saw your post, i changed the .html() to .text() and yes it got rid of the magical divs... awesome... its a step forward now and not backwards haha... now just to do some tweaking so it will keep new lines with <br> which should be simple enough :P

i see...


so when using .text() if my content looks like this





My Name is Guber

it will display like this



Hi!My Name is Guber


now for my rich text editor, it kinda defeats the purpose of being a "rich text editor" if you need to add html into the content before submitting.

Just for everyone to see how I fixed my issue. it was due to jquery.


this section

	$("#submit").click(function() {

i had to add a .replace after the .html so it looks like this and solved my issue

	$("#submit").click(function() {

yes I went back to using .html(), the .text() was being difficult to work with and the above script solved my problem :)


Thanks to all who have helped me out, got me pointed in the right direction. thank you :)
