Checking an Array for interjection..

imnsi

Its my first time using array_walk to go thru a list of variables to test for any interjection... the question I have is: is there a function/method to have a dynamic variable set to a variable.... see ******

I want to have it loop thru all and set them back to their original names but check for strip slashes.

the values come from a form, I removed a $ in front of them to try and get php to load them dynamically from an array... plz help so lost :-/

any insight is kindly appreciated.


//check values for interjection and errors
$valuestocheck = array('key', 'signSize', 'numberOfSides', 'numberOfColors', 'materialType',
 'halftone', 'doublesided', 'yellowbg', 'quantityOfSigns', 'quantityOfStakes', 'signsPrice',
 'stakesPrice', 'shipPrice', 'totalPrice', 'shippingFullname', 'shippingAddy1', 'shippingAddy2',
 'shippingCity', 'shippingState', 'shippingCountry', 'shippingPostalCode', 'shippingPhone', 'email', 'personalFullname',
 'personalAddy1', 'personalAddy2', 'personalCity', 'personalState', 'personalPostalCode', 'personalCountry', 'personalPhone', 
 'cardType', 'designid', 'uploadedFile', 'comment', 'date');

function checkValues ($name){

$name = stripslashes($_GET['$name']);

};

array_walk($valuestocheck, 'checkValues');

I'm not sure what you're trying to do ("not sure" as in "don't know"), but I think achieving it will involve removing the single quotes from "$_GET['$name']". They cause PHP to look for an array index named "$name" rather than one named by the value for "$name".

Do you mean "injection" instead of "interjection"?

If, as Installer suggests, you mean "How do I trap sql injection attacks?" then the answer is to be found in mysql real escape string . Read it and use the 'Best Practice' code that you'll find there.

I appreciate both responses, I meant injection yes.. lol. I musta had an extra coffee..

Maybe its better if I ask this question.. If I wanted to name the following variable names listed in the following array.. If I wanted to give them all a value of "completed" how would I do that..

$variablesArray = array('schoolwork', 'homework', 'project4');

function markComplete ($currentVariableName){

$currentVariableName = 'completed'; //how do I set variables dynamically?

};

array_walk($variablesArray, 'markComplete');
