  Bug report --- "TypeError: str.replace is not a function" (Copied from FireBug)

// PHPJS cannot parse the following codes, while it's possible in PHP
parse_str('&first=foo');
parse_str('first=foo&');
parse_str('&first=foo&');

  @ droope: Although there are plenty open jslint issues with this function, i is actually defined and in my tests it works. What platform are you experiencing issues on?

  Hi.

I keep getting "i is not defined". Perhaps something broke?

Regards,
Droope

  Thanks much, stag019... Fixed in SVN (including moving equality operators to identity ones)...

  Two things I forgot to mention:
Depends on urldecode now.
Some places I use '==' or '!=' where I could probably use '===' or '!=='. These should probably be fixed.

  Well, time to bugfix myself. ;P

Looking through the PHP source I realized I completely neglected to test anything with a null character in it. Aparently PHP completely ignores everything after a null character in the key name, but leaves it alone in the value.

Change the function fixStr to

return urldecode(str).replace(/([\"'])/g, '\\$1').replace(/\n/g, '\\n').replace(/\r/g, '\\r');

Underneath

		while(key.charAt(0) === ' ')
		{
			key = key.substr(1);
		}

add

		if(key.indexOf('\0') !== -1)
		{
			key = key.substr(0, key.indexOf('\0'));
		}

  Looks good, stag019, thanks! Added in SVN. (Netbeans just caught the fact that "chr" needed to be declared too.). If you like, you might also consider voting for https://bugzilla.mozilla.org/show_bug.cgi?id=488227 as this is one behavior JS can't emulate from many PHP functions (in this case, we'd get a way to use parse_str() to put variables into a local scope only without using an array).

  Oops, I also forgot to mention that the second parameter is now optional, as it uses the window variable if none is defined.

  Sure, it parses strings such as array[key]=value into an array, in the same fashion PHP does. It also handles the encoding of the period and space characters, in the same fashion that PHP does.

  stag019: Sorry but there are a lot function we need to maintain. Would it be possible for you to explain how your implementation beats our current one?

  I couldn't think of a way to do it without eval(), but it better emulates PHP.

function parse_str(str, array)
{
	var glue1 = '=', glue2 = '&', array2 = String(str).split(glue2),
	i, j, tmp, key, value, bracket, keys, evalStr,
	fixStr = function(str)
	{
		return urldecode(str).replace(/([\"'])/g, '\\$1').replace(/\0/g, '\\0').replace(/\n/g, '\\n').replace(/\r/g, '\\r');
	};

	if(!array)
	{
		array = window;
	}

	for(i = 0; i < array2.length; i++)
	{
		tmp = array2[i].split(glue1);
		if(tmp.length < 2)
		{
			tmp = [tmp, ''];
		}
		key   = fixStr(tmp[0]);
		value = fixStr(tmp[1]);
		while(key.charAt(0) == ' ')
		{
			key = key.substr(1);
		}
		if(key && key.charAt(0) != '[')
		{
			keys    = [];
			bracket = 0;
			for(j = 0; j < key.length; j++)
			{
				if(key.charAt(j) == '[' && !bracket)
				{
					bracket = j + 1;
				}
				else if(key.charAt(j) == ']')
				{
					if(bracket)
					{
						if(!keys.length)
						{
							keys.push(key.substr(0, bracket - 1));
						}
						keys.push(key.substr(bracket, j - bracket));
						bracket = 0;
						if(key.charAt(j + 1) !== '[')
						{
							break;
						}
					}
				}
			}
			if(!keys.length)
			{
				keys = [key];
			}
			for(j = 0; j < keys[0].length; j++)
			{
				chr = keys[0].charAt(j);
				if(chr == ' ' || chr == '.' || chr == '[')
				{
					keys[0] = keys[0].substr(0, j) + '_' + keys[0].substr(j + 1);
				}
				if(chr == '[')
				{
					break;
				}
			}
			evalStr = 'array';
			for(j = 0; j < keys.length; j++)
			{
				key = keys[j];
				if((key !== '' && key !== ' ') || j === 0)
				{
					key = "'" + key + "'";
				}
				else
				{
					key = eval(evalStr + '.push([]);') - 1;
				}
				evalStr += '[' + key + ']';
				if(j != keys.length - 1 && eval('typeof ' + evalStr) == 'undefined')
				{
					eval(evalStr + ' = [];');
				}
			}
			evalStr += " = '" + value + "';\n";
			eval(evalStr);
		}
	}
}

  @ Michael White: great! thank you!

  This function did not take into account the fact that the URL string might be encoded so I modified it to handle encoded URLs and added a new example.


[CODE="JavaScript"]
function parse_str(str, array){
// http://kevin.vanzonneveld.net
// + original by: Cagri Ekin
// * example 1: parse_str('first=foo&second=bar');
// * returns 1: { first: 'foo', second: 'bar' }
// * example 2: parse_str('str_a=Jack+and+Jill+didn%27t+see+the+well.');
// * returns 2: { str_a: "Jack and Jill didn't see the well." }

var glue1 = '=';
var glue2 = '&';

var array2 = str.split(glue2);
var array3 = [];
for(var x=0; x<array2.length; x++){
var tmp = array2[x].split(glue1);
array3[unescape(tmp[0])] = unescape(tmp[1]).replace(/[+]/g, ' '); // This is the modified line.
}

if(array){
array = array3;
} else {
return array3;
}
}
[/CODE]
