cougarreddy Posted July 6, 2009 Share Posted July 6, 2009 Hi, i am doing a web-application, where user requests access to a building. User goes to the application and fills out an access request form. Once the request is submitted, it should be accepted by his supervisor before access is given by the authorities. So, I am planning to do it like this. Once request is submitted application should send an email to user's supervisor with all the details in the form and two links, one for accept request, other for reject request. link contains a random number created for that particular record. once the accept link is clicked, using random number in the url, record is modified as accepted or rejected. i want to know, how to generate a big (may be 10 digits)random number which is not so easy to guess? and is it better to have a combination of alphabets and numnericals or only numericals is enough? Thanks in advance Quote Link to comment Share on other sites More sharing options...
elis Posted July 6, 2009 Share Posted July 6, 2009 Try <?php $key = substr(md5(rand(0, 1000000)), 0, 10); //generates an alphanumeric code ?> and use $key wherever you want it to show. Quote Link to comment Share on other sites More sharing options...
