Why it is showing error Undefined Index....???

[Ch0cu3r]

Can you post the full error message.

[Barand]

Also note the the use of session_register() was replaced by $_SESSION in December 2001.

Can you post the full error message.

This is the complete error....!!!!

Notice: Undefined index: er_id in C:\xampp\htdocs\job\login_parse.php on line 99

Also note the the use of session_register() was replaced by $_SESSION in December 2001.

But still not working after removing session_register()....!!!!

[mac_gyver]

the error is self explanatory, it means that you are referencing an array index that doesn't exist.

 

since the only reference to an array index by that name is in this line - $er_id = $row1["er_id"];, does your database table have a column named er_id?

 

also, why do you have two database tables, one for employees and one for employers, and double the amount of code? that's not how to program. the visitors that are logging in shouldn't need to pick which type they are on the form page. all they should need to do is enter their email and password. it should be up to your single database table and your code to know what type they are. by having two tables, you are have to write, test, and debug double the amount of code for the form and for the form processing.

 

lastly, the mysql_ database functions are obsolete and will be removed from php in the near future. you should be learning to use either the PDO or mysqli_ database functions so that what you are learning isn't already out of date.

Perhaps you could point out the line that is giving you the error message since line 99 in your post is blank.

 

No need to get indignant - you were simply asked for a more complete details to help solve your dilemma.

 

PS - if you removed all the uses of session_register, what did you replace them with? Perhaps you could post your revised code - specifically the area where you are having the problem?
