Trouble with brackets in arrays..

[dreamclutch]

I'm having a bit of trouble with this one. I've got conflicting array brackets and was curious how to break it apart programmatically so that is functions correctly.

The problem exists at the form action below. I'm including javascript at the end of the post action so that it checks the javascript wordFilter function below. That's fine and dandy but the name fields which I'm retrieving ALSO have brackets.

Normally the onsubmit code would look like the following under the form action and would work:

onSubmit="return wordFilter('form1',['word9','word82', 'etc.'])";>

however the names that I need to use include brackets within the text field names, e.g. word[9] and word[82], etc. like below.

onSubmit="return wordFilter('form1',['word[9]','word[82]','etc[]'])";>

Thanks

 swear_alert_count=0;

You should not use // for comments outside of script section. Replace them with <!-- -->, I have not replaced all, only one or two! Do it by yourself.

The actualy field names below the post action are already parsed. I'm not sure why I included php brackets around that bit of code. The field names for the text fields are parsed from a previous script...the bit of php that uses the array.

When I submit I'm getting the following javascript error.

Line 76
Char 3
document.form1.word is null or not an object.
