Re: Handling HTML special chars from user generated content ( e.g. forms)
i dont see the reason for changing them to HTML code anyway - as with
utf8 they can all be handled and displayed as they originally are.

I was messing with this problem the whole day and never thought it
would be that simple :).
Thank you so much for this simple solution!

Hi,
do you use the form helper?
If so try something like this:
$form-input('foo.bar', array('escape' = false))

Another explaining example for the edit form:
http://localhost/regions/edit/15
data['Regions']['id']=15
data['Regions']['name']='Test auml;'
Now when cakephp fills the form with this data the value of the field
changes from
'Test auml;' to 'Test amp;auml;'
And so the field shows 'Test auml; instead of 'Test ä'
Is there any way to tell cakephp not to check for specialchars?
Maybe now there is some help? :P

Handling HTML special chars from user generated content ( e.g. forms)
Hi bakers,
as by the last week i am really getting into CakePHP and enjoy the
easeness of the creation process.
But i have one simple problem.
In every form of the project where users can input data, they can for
example input ( ä,ö,ü, é... and special chars like %§%/ or whatever)
So i want to write a system function that converts all these chars to
their html form. That is for example a ä becomes auml; etc.
To approach this i already wrote a function that does this exactly:
function htmlizeArray($txtArray) {
if (is_array($txtArray)) {
foreach ($txtArray as $key = $val) {
htmlizeArray($val);
}
}
else {
$txtArray = htmlentities($txtArray);
}
}
So now i have to know where to put this function in the source to
access it from every controller that i have made.
Because in the controllers where i anyhow deal with posted form data i
want to htmlize the data.
All the form data from a specific view is in the controller accessed
by $this-data.
So what i want to do now is to htmlize it with
htmlizeArray($this-data);
So maybe you can help me out with it.
Greetings from Germany

Re: Handling HTML special chars from user generated content ( e.g. forms)
Hi bakers again :),
i managed to do it another way.
These two function provided below are the key for it. As you can see I
placed them inside of the app_controller.php
class AppController extends Controller {
function htmlchars($data) {
if (empty($data)) {
return $data;
}
if (is_array($data)) {
foreach ($data as $key = $val) {
$data[$key] = $this-htmlchars($val);
}
return $data;
}
else {
$patterns = array(/\/, /%/, //, //, '//',
/'/, /\
(/, /\)/, /\+/, /-/, /ä/, /Ä/, /ö/, /Ö/, /ü/, /Ü/);
$replacements = array(amp;, #37;, lt;, gt;,
quot;,
#39;, #40;, #41;, #43;, #45;, auml;, Auml;,
ouml;, Ouml;, uuml;, Uuml;);
$data = preg_replace($patterns, $replacements, $data);
return $data;
}
}
function unhtmlchars($data) {
if (empty($data)) {
return $data;
}
if (is_array($data)) {
foreach ($data as $key = $val) {
$data[$key] = $this-unhtmlchars($val);
}
return $data;
}
else {
$patterns = array(/amp;/, /#37;/, /lt;/,
/gt;/, /
quot;/, /#39;/, /#40;/, /#41;/, /#43;/, /#45;/, /
auml;/, /Auml;/, /ouml;/, /Ouml;/, /uuml;/, /Uuml;/);
$replacements = array(, %, , , '', ',
(, ), +,
-, ä, Ä, ö, Ö, ü, Ü);
$data = preg_replace($patterns, $replacements, $data);
return $data;
}
}
}
So if i retrieve any data for a view i simply do $cleandata = $this-
htmlchars($this-data); and use $cleandata for now on.
The same with unhtmlchars().
The only problem i have now is the following.
Lets say I have an edit form with a Name field.
If the Name contains no special chars like ä,ö,ü etc. the value
of the field is filled automatically through the $form helper, but if
the Name contains one of those special chars, the field is not filled.
I don't know how to solve this.
Please help me as I'm stuck here.
Thanks in advance
worthy
