hi,

i have a problem using EE native checkbox field in Safecracker form. When clicking Submit i get this error: “Disallowed Key Characters.” What’s wrong here?

Dmitry

my code:

{exp:safecracker channel="read" return="read/thanks" url_title="{segment_3}" id="edit_tab_form" safecracker_head="yes" include_jquery="no"}    

{custom_fields}
{if checkbox}
{options}
<label class="checkbox">{option_value}
<input type="checkbox" id="{col2}" name="{col2}[]" value="{option_value}"{checked}/>
</label>
{/options}
{/if}
{/custom_fields}

<input type="hidden" name="allow_comments" value="y" {allow_comments} />
<input type="submit" value="{bbr-mls-save}" class="button_m"/>

{/exp:safecracker}

Hi Dmitry,

Your SafeCracker code all looks good for the time being, can you post the html source that is being output by the template? That’s where the “Disallowed” characters would be displayed.

Cheers!

hi Dan,

Html source is the same “Disallowed Key Characters.” nothing else. I also tried:

{exp:safecracker channel="read" entry_id="1158" dynamic="no"}

- the same result. Can you test this code on your EE 2.2.2 install?

what is also strange: ee native checkbox field won’t show up in exp:channel:entries tag. (single or pair, both) Will you have a chance to test it?

EE2.2.2

Dmitry,

I would love to be able to test this out for you, however my setup wouldn’t mimic your’s closely enough to repeat the errors. The “Disallowed Key Characters” has something to do with either the value of {segment_3} or the value of {col12}

Can you share with me what those values are?

Thanks,

i changed url_title to entry_id, the same error:

{exp:safecracker channel="read" entry_id="1158" dynamic="no"}

The checkbox value “two column”, i tried different values though.

just tested on EE 2.2.1 - the same error.

Dmitry,

I think the “space” in “two column” might be the issue. Did you try any values without a space character?

Best,

nope,

the strangest thing i found: using numbers in a field name (for checkboxes) brings that error. After that revelation, another bug appeared: the value of checkbox won’t save on submit. At that moment, i gave up on native ee fields and tried PT checkbox (Brandon Kelly’s a parent) and it worked fine from the first second. The value for that pt checkbox can be 2 words and even in russian (here’s for your test if you fancy: хороший чекбокс)

too bad you didn’t have a chance to test it on your install.. i want to know is it a bug or just my own issues.

Hey Dmitry,

I’m glad you figured out a work around. Now that I have a little more information about the characters you’re using in the native checkboxes, I’ll see if I can replicate. I’ll follow up here with my findings 😊

Cheers,

ok thanks!
it was a challenge to make it work both in exp:channel:entries tag and in safecracker form and i didn’t succeed. it’s funny how simple checkbox can drive someone crazy -)

hi Dan,

did you have a chance to test a checkbox in safecracker to make sure: 1) it will save the value in an entry 2) the value can be two words separated with space?

Dmitry,

Like Dan mentioned, you might double check the value for your field name and other attributes in:

<input type="checkbox" id="{col2}" name="{col2}[]" value="{option_value}"{checked}/>

I was getting the same error of “Disallowed Key Characters” when I submitted my safecracker form with checkbox inputs.  It turned out I was accidentally using a hash “#” sign in my field name, which is filtered out by EE.

The form submitted fine after I removed the hash, and I’m even using numbers in my field names for the checkboxes.

For the issue of your checkboxes not saving, try using the following parameter for safecracker:

preserve_checkboxes="yes"

Thanks FarmBoy ! I’ll try that idea on a fresh EE install..

Dmitry,

Please let us know how the fresh install goes. I’m going to move this over into Community Help to keep the discussion open. As always, start a new thread anytime you need assistance.

Cheers!
