from WYSIWYG edito into mysql. htmlspecialchars or trim?

[php_guest]

Please help with about the following questions. I would like to save data from WYSIWYG into mysql and create preview before that.

 

Question 1:

If I understand right the trim function makes that php ignore character ",' etc. and they are still shown in html. The htmlspecialchars change those characters with others to not confuse php. I am right?

 

Question 2:

I tried both of functions and I have still a problem.

echo "<form action='nov.php' method='post'><input type='hidden' name='content' value='".$content."'><input type='submit' name='submit' value='Back to edit'></form>";

 

shows '>submit button instead only Back to edit submit button. Did I miss anything?

 

Thank you

see these links for the explanation of the functions:

as of the second question I do not understand how it related to trim() or htmlspecialchars() functions since you use these functions before inserting data into mysql while the line you posted is to display the form straightaway from the php code.

 

anyway try this code and see if its working:

echo "<form action='nov.php' method='post'><input type='hidden' name='content' value='$content'><input type='submit' name='submit' value='Back to edit'></form>";
