Error when deleting or editing form data from database using PHP and MySQL

Question

Everything in my code seems to work just fine, except when I try to edit/delete already queried data.

Delete does nothing... and edit gives me an error shown below:

First of all, use prepared Statements to prevent SQL injection. Now to your error:

The table Employer has no column eid:

CREATE TABLE IF NOT EXISTS `Employer` (
  `EmployerID` int(60) NOT NULL,
  `CompName` varchar(60) NOT NULL,
  `Address` varchar(20) NOT NULL,
  `Phone` int(10) NOT NULL,
  `Email` varchar(30) NOT NULL,
  `PosTitle` varchar(30) NOT NULL,
  `Description` varchar(100) NOT NULL,
  `Location` varchar(35) NOT NULL,
  `Skill1` varchar(20) NOT NULL,
  `Experience1` int(10) NOT NULL,
  `Skill2` varchar(20) NOT NULL,
  `Experience2` int(11) NOT NULL,
  `Skill3` varchar(20) NOT NULL,
  `Experience3` int(11) NOT NULL,
  `Need` varchar(15) NOT NULL,
  PRIMARY KEY (`EmployerID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

The column name you refering is named EmployerID.

So your statement must be delete from Employer where EmployerID=$eid.

And because employerId is an int not a character field you do not need the single quotes arround.

The same error is in the following select statement.

Then you mix mysqli_* API and mysql_* (mysql_errr()). Change it to mysqli_error
