save html-formatted text to database
I want to save html-formatted text to database, but when I do that it is don't save html-symbols like < / > ' and others This is how I read article from database for editing:
<p class="Title">Англійський варіант:</p>
<textarea name="EN" cols="90" rows="20" value="<?php echo htmlentities($articleArr['EN'], ENT_QUOTES, "UTF-8"); ?>" ></textarea>
after this generates such html-code:
<p class="Title">Англійський варіант:</p>
<textarea name="EN" cols="90" rows="20" value="<p class='T开发者_如何学Goitle'> привыт </p>" ></textarea>
So, I expect that this text will appear in my text field, in html-code of this page it is, but in text area is no.
In database I save it as:
<p class="Title"> Hello </p>
So how can I do the follow:
- Read from database html-formattedtext.
- Show it in textarea element.
- Edit and save it back to database.
Help me please, how can I save such texts properly, Thanx!
Try using htmlspecialchars()
on the string to put into the DB, and then, when pulling it back out, use htmlspecialchars_decode()
. Might make a difference.
Save it to a nvarchar(max) field.
Make sure you use parameterized queries for security. Read

with little changes to Sql , you can apply to Mysql aslo
there is no problem with save your html code in database. and no need for filter data before save .
but when you want to show it again in textarea
you shoud Escape
it.
in php you can use this code to escape html codes:
PHP Function
see doc: htmlspecialchars
$cotnent = htmlspecialchars( $cotnent );
Wordpress Functions:
see doc: format_to_edit
$cotnent = format_to_edit( $cotnent , false );
OR
see doc: esc_textarea
$cotnent = esc_textarea( $cotnent );
