Paid on delivery
We are updating php from 5.4 to 5.6 and need someone to update the mysql_ to mysqli_ logic in some php functions on the attached pages. You should be familiar with: mysqli_connect() mysqli_real_escape_string() mysqli_error() mysqli_errno() ...and others used in the scripts. We are seeing these messages among others in the logs: - PHP Warning: mysqli_real_escape_string() expects parameter 1 to be mysqli, null given in -[07-Nov-2016 11:09:51 America/Tegucigalpa] PHP Warning: mysqli_real_escape_string() expects parameter 1 to be mysqli, null given in application\controller\[login to view URL] on line 1886 This task should be of interest to a skilled php developer familiar with the syntax differences between these php versions and able to make the changes in the file, return the file to us, we will test and debug and troubleshoot with you. We will not be able to give access to the codebase or ftp. Any questions please message me. Thanks Henry

Hi, Mysql extension is deprecated which is why you're getting that error - I can replace all your existing mysql functions calls with mysqli extension so it works well with newer versions of php (I've built a number of php apps, and i always use PDO or mysqli ..) Thanks!

Hello Henry. My name is Dobri, I looked through the three files attached and this would not be any problem to convert. Although modding remotely(without access to the actual setup this would run onto) is not a problem, it does involve a somewhat greater deal of uncertainty as no direct/immediate tests fixes could be applied, but assistance from you would be required to carry out those, meaning much more time to finish as well as a possibility for 'hidden'(as of now) more work as well, so I am betting the safe bet here bidding slightly more I would have if I had direct access. I hope that won't discourage you towards chosing me for the job. Can start rewriting those two in about one hours time. Kind Regards, Dobri

Hello, I am PHP and database coder and analyzed your php code. The message tells you that the problem is parameter 1 provided to mysqli_error. Obviously you didn't declare it and assign anything to it, because I couldn't find any declaration of "$this->dbObject" in your code. In the first parameter of mysqli_real_escape_string you set the connection to the database. In your case it's NULL - so there's your problem ;) Kind regards, Ozzy

I have over 10 years experience with PHP, and I assisted my most recent employer, Shoe Carnival, in performing a similar upgrade. There were hundreds of lines of code in production programs that needed to be adjusted once PHP was upgraded on the server. I could definitely get this done for you with a quick turn-around time. I would love the opportunity to work with you on these modifications, or any other development work you may need. I appreciate your consideration. Thanks.
