How Do You Deal With ', Single Quote In Person's Names In Php, Javascript

I noticed that some of name entries, like O'Rourke or O'reilly breaks javascript in some cases. I wonder how you deal with it. I pull these names out of PHP/MYSQL and put them in j

Solution 1:

You're going through a lot of messy and error-prone string-appending work just to output a javascript variable. What you should do instead is build the data structure you want in PHP (an array of arrays) and then use json_encode() to emit a javascript-compatible literal. All quotes and such will be automatically escaped by the encoder.

$itemOutput = array();
if(count($items)) {
    foreach($items as $item) {
        foreach($advisors as $key=>$advisor) {
            if($item['advisor']==$advisor['id']) {
                $ad=$advisor['last_name'];
            }
        }
        $active_icon = ($item['active']=='1'?'tick':'cross');
        $editlink = anchor('auth/admin/members/form/'.$item['id'],$this->bep_assets->icon('pencil'));
        $itemOutput[] = array(
            $item['first_name'],
            $item['last_name'],
            $item['email'],
            $item['parent_email'],
            $item['parent_email2'],
            $ad,
            $this->beep_assets->icon($active_icon),
            $editLink
        );
    }
}
echo "data.addRows(" . json_encode($itemOutput) . ");" ;

If you have an object or an associative array, it gets emitted as a javascript object:

echo json_encode( 
    array( 'a'=>'aa', 'b'=>'bb'),
    array( 'c'=>'cc', 'd'=>'dd')
);
==> [{"a":"aa","b":"bb"},{"c":"cc","d":"dd"}]
