I have a text box with this code:

<textarea name="link_rt" id="link_rt" rows="4" class="text-intput text-box" onKeyDown="limitText(this,140);" onKeyUp="limitText(this,140);"></textarea>

Open in new window


My Mysql insert code is:

$query = "INSERT INTO di_links (link_id, linkType, linkText) VALUES ('".$postId."','RT','".mysql_real_escape_string($link_rt)."')";

Open in new window


if a person types in a & or # the text gets cut off at that point when inserting into the database.  How can i have special characters into a database field?

Use htmlspecialchars( $link_rt, ENT_QUOTES )

See http://www.php.net/htmlspecialchars

Actually, on reflection a & or a # should not prevent the SQL statement from completing. Are you sure that the javascript limitText is not the culprit here?

so would you do that in the variable declaration in my query page?

like:

$link_rt = htmlspecialchars( $_POST['link_rt'], ENT_QUOTES );

Try it and see - just like you typed, but I think the problem is elsewhere. Does anything else process $link_rt before it gets to the query?

the data is going into the DB but when you view it again you need to use htmlspecialcharacters to display it, check the DB directly to see if its there correctly

its not even getting in the database.. im finding out through searches that it has to do with $.ajax submitting the form feilds dynamically.. and its not escaping the ampersand... still trying to find out how to fix it because that is the only character that is having the problem right now.

sorry im kind of new at this a bit.  Here is my Ajax code

submitHandler: function(form) {

			 var link_rt     = $('#link_rt').attr('value');
			 var link_ts     = $('#link_ts').attr('value');
			 
			 				
		$.ajax({		
						type: "POST",
						url: "/action/submit.php",
						data: { link_rt: link_rt, link_ts: link_ts },
						success: function(){
						$('form#submitForm').hide(function(){$('div.success').fadeIn();});
						document.getElementById("submitForm").reset();
						setTimeout($('form#submitForm').show(function(){$('div.success').fadeOut();}),4000);
						}
		});

Open in new window


here is my Php insert

$link_rt = urlencode($_POST['link_rt']);


$query = "INSERT INTO di_links (link_id, linkType, linkText) VALUES ('".$postId."','RT','".mysql_real_escape_string($link_rt)."')";

Open in new window


any idea what could be wrong with ampersand characters getting cut off from the ajax page to the php insert?
