[SOLVED] Concatenation

[skicrud]

Does anyone know the proper syntax for $_POST['C_'$var]?

 

I need to concat the variable name of a post with a prefix and I keep getting syntax errors.

[Maq]

Use a dot, just like any other string.

[mandred]

$_POST['C_' . $var];

 

or

 

$_POST["C_$var"];

[skicrud]

the  $_POST[C_.$var] produces the following error:

Parse error: parse error, expecting `']''

and the $_POST['C_$var'] returns this error:

Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING'

[Maq]

You're missing single quotes.

[skicrud]

Where?

[Maq]

Please read previous posts, mandred provided you with the exact answer...

 

$_POST['C_' . $var];

Both things you tried do not match the examples that were posted. Go back and read the examples. Where quotes are and if they are single-quotes or double-quotes matters in programming because computers only do exactly what your code tells them to do.

[skicrud]

echo "insert into log job_number=$job_number, user=$theid, item_checked=$key, item_comment=$_POST['C_'.$var]"; produces an error

but

echo "insert into log job_number=$job_number, user=$theid, item_checked=$key, item_comment=";

echo $_POST['C_'.$var];

does not.

[Maq]

Please use

tags around code.

 

You never mentioned it was in a query...

 

Try:

 

echo "insert into log job_number=$job_number, user=$theid, item_checked=$key, item_comment='{$_POST['C_'.$var]}'";

Sorry and thanks

Sorry and thanks

 

You're still new here, don't worry about it.  It just makes the code easier to read by formatting and highlighting code properly.

 

If everything properly works now, please mark as [sOLVED].
