I’m building a file uploader that gets IPTC data from the image and inserts it into a db but I keep getting this error:<\/p>\n

> A PHP Error was encountered\n> \n> Severity: Notice\n> \n> Message: Undefined index: 2#120\n> \n> Filename: controllers\/upload.php\n> \n> Line Number: 63\n<\/code><\/pre>\n
Here’s the line from the controller:<\/p>\n
$iptc_description = $iptc[\"2#120\"];\n<\/code><\/pre>\n
The script works perfectly as it’s supposed to, but it keeps throwing up this error and I can’t figure out why.<\/p>\n
    \n
  1. \n
    Replace that line with (your using the variable before its set):<\/p>\n
    $iptc_description = (isset($iptc[\"2#120\"]))?$iptc[\"2#120\"]:null;\n<\/code><\/pre>\n
    Or if you don’t like one-liners:<\/p>\n
    $iptc_description = null;\nif (isset($iptc[\"2#120\"])) {\n    $iptc_description = $iptc[\"2#120\"];\n}\n<\/code><\/pre>\n<\/li>\n<\/ol>\n
