Passing Form Variables to SQL

[DennisFaucher]

Hello,

I am passing variables to my CanvasJS chart PHP from a web form

This SQL works

$handle = $link->prepare(‘select ext_rev as x, discount as y from mysql.ne_nj_tbl where pnl like \’Commercial NE Majors%\’ and manuf like \’CISCO%\”);

This SQL fails

$handle = $link->prepare(‘select ext_rev as x, discount as y from mysql.ne_nj_tbl where pnl like \’$pandl%\’ and manuf like \’$manuf_var%\”);

I have used that SQL successfully in another PHP script but not with CanvasJS. Any ideas? TIA.

@dennisfaucher,

There seems to be an issue with the MySQL query which you are performing.

If you are unable to resolve the issue, kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive along with the sample database so that we run the code locally, understand the scenario better and help you out?

@shashiranjan, thank you.

The data fields are not important, it is passing web form variables to the SQL statement that I need help with.

The PHP web form I am using is here: https://www.dropbox.com/s/7w2d7gy6nxaolex/inn_scatter_disc_entry.php?dl=0
The CanvasJS PHP with the SQL statement is here: https://www.dropbox.com/s/t1vhw82rfl947nr/inn_scatter_disc.php?dl=0

Here is an example of working PHP passing a web form to a SQL statement:

PHP web form: https://www.dropbox.com/s/et2p8nvft9e38y9/detail_entry.php?dl=0
Tabular result based on SQL: https://www.dropbox.com/s/r87ecj679ctejq4/detail_mysql.php?dl=0

Thank you.

@dennisfaucher,

Can you kindly create a working sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive with the sample database and PHP files so that we can run the code locally, understand the scenario better and help you out?

Fixed it. Yay.

$pandl = $_POST[“pl”];
$manuf_var = $_POST[“oem”];

$sql_var=”select ext_rev as x, discount as y, customer as z, manuf as w from innovation.ne_nj_tbl where pnl like ‘$pandl%’ and manuf like ‘$manuf_var%'”;

$handle = $link->prepare($sql_var);
