I do understand that if you were in the middle of a php script, this would be a simple reassigning of the variable. However, this is a preprocessor command, and thus should be handled a little differently. Adding a "[]" at the tail of a variable and having it come out as an array on the other end seems a like a trick. It has its uses I'll give you that, but if you look at my suggestion you will realize that it would be a nice feature. You guys seem to have take the time to make sure that elements with "[]" get properly shoved into arrays, so why not this. This is a fairly common situation in html forms. Especially if you are dynamically generating them. What this really comes down to is, are you willing to overlook the fact that something like this does sort of already exist, in favor of another form of functionality? There is one other issue. If you use the variable names that you suggest, it breaks javascript. ie: <html> <body> <form name="form1" action="" method="post"> Baseball: <input type="checkbox" name="interest[]" value="baseball"> <br> Teams: <input type="text" name="teams[]" size="30" onFocus="form1.interest[0].checked=1"> <br> <input type="submit" value="submit"> </form> </body> </html> will cause an error, because you don't define arrays in javascript this way. I realize that this seems like a bug in javascript, but actually it isn't. The html 4.01 specification clearly states that: "ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".")." Note: this does not suggest that you can add "[" or "]". So, in essence you are violating the html specification. If you still do not agree that this would only improve php, I will stop bothering you.

Image when you write the following code in php: $interests = "something"; $interests = "new"; Would you expect this ending up with $interests being an array("something", "new"); ? Certainly not. So, for you to have an array, like Jani said, append '[]' and you have what you want. - Markus ------------------------------------------------------------------------ [2001-10-17 22:19:52] [EMAIL PROTECTED] Here is an example of what I am talking about, try to imagine the interests being dynamically generated, because it is easy if you already know the names of all of the elements and the form itself: form.html: <html> <body> <form action="post.html" method="post"> Baseball: <input type="checkbox" name="interests" value="baseball"><br> Teams: <input type="text" name="teams" size="40" onFocus="interests[0].checked='1'"><br><br> Football:<input type="checkbox" name="interests" value="football"><br> <input type="submit" value="Submit"> </form> </body> </html> post.html: <html> <body> <?php /** * This is how it should work, interests should be an array **/ echo("interest 1: $interests[0]<br>\n"); echo("interest 2: $interests[1]<br>\n"); /** * Instead, the value of $interests is that of the last * value posted. **/ echo("$interests"); ?> </body> </html> ------------------------------------------------------------------------ [2001-10-17 20:10:49] [EMAIL PROTECTED] Just name them as 'name=varname[]' (add the []'s in the end) and you'll get an array. --Jani ------------------------------------------------------------------------ [2001-10-17 16:47:11] [EMAIL PROTECTED] The problem exists in the way that php handles the reception of a posted form. If there is more than one element in a form with the same name and it is posted to a php page, php handles this by assuming the last element with that name is the correct value for that variable. In order to provide a proper coexistance with javascript it should treat all variables with that name as elements of an array. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=13718&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
