Zend_Form has problem with swedish characters
Posted on 2010-08-19
This code is supposed to render four cities in a dropdown in the viewscript (not shown here):
But the html output is:
See the pattern here..?
<?php
class Application_Form_Editprofile extends Zend_Form
{
.
.
.
public function init()
{
$this->setMethod('post');
$eCity=new Zend_Form_Element_Select("city");
$eCity->setLabel("[please set label in view]");
// $eCity->setMultiOptions($this->cities);
//TEST CODE HERE:
$kalle=array(4=>"Stockholm",7=>"Eskilstuna",12=>"Göteborg", 77=>"Malmö");
$eCity->setMultiOptions($kalle);
$sfCity=new Zend_Form_SubForm();
$sfCity->addElement($eCity);
$this->addSubForm($sfCity, "city");
}
}
But the html output is:
<form enctype="application/x-www-form-urlencoded" method="post" action=""><dl class="zend_form">
<dt id="city-label"> </dt><dd id="city-element"><fieldset id="fieldset-city"><dl>
<dt id="city-label"><label for="city-city" class="optional">Stad</label></dt>
<dd id="city-element">
<select name="city[city]" id="city-city">
<option value="4" label="Stockholm">Stockholm</option>
<option value="7" label="Eskilstuna">Eskilstuna</option>
<option value="12" label=""></option>
<option value="77" label=""></option>
</select></dd></dl></fieldset></dd></dl></form>
See the pattern here..?

>>Pass the output through htmlentities().
Ok, let's see..
The view script attached will render:
<form enctype="application/x-www
Same same ;)

//echo $this->form;
echo htmlentities($this->form) ;

Ok, may be you meant like this ;)
Still quite doesn't work though.

I'd like to think that Zend is doing a re-encoding as long as it can read the original.
Probably, the special characters come in a strange encoding from the database?
You should try and align the encoding settings of database and Zend, ie. both UTF-8 or whatever fits best.

The values are hard coded in this example and do not come from db.
How do you "set encoding in Zend"?
(main layout.phtml is set to iso-8859-1)

From the look of the PNG image above, it looks like the character strings are being entitized as they are put into the dropdown list. This looks like the output of a double trip through htmlentities(). You did it once with this:
12=>htmlentities("Göteborg
And something in the Zend code did it again.
Not sure what EE will do with the next line, so I will post a small code snippet, too.
G&ouml;teborg
It looks like something in the class Zend_Form_Element_Select or perhaps Zend_Form_SubForm is "helping" you by removing fields that contain unusual characters. You might consider using var_dump() to print out the objects are they are created. Then you might be able to find the "helper" code that is deleting the strings. This does not look so much like an encoding question as a simple programming error. Almost as if a ctype filter is applied to the entire string and if any character fails, the string is deleted (instead of the bad character).

<?php // RAY_temp_zend_utf8.php
error_reporting(E_ALL);
echo "Goatberg";
echo "Göteborg";
echo htmlentities("Göteborg");
$g = htmlentities("Göteborg");
echo $g;
$h = htmlentities($g);
echo $h;
echo "<br/>VIEW SOURCE";
Still guessing here, but have a look at the man page notes.
http://us2.php.net/manual/en/function.ctype-alpha.php
An interesting test might be a city named "foo!#$bar\t".

Workaround invented.. :)
A better solution, anyone?
It's these kind of things you're using ZF for to avoid..

What a hoot! You should copyright this just to annoy the Zend developers ;-)

Actually you can boil it down to this:
