hi below is the code i am using to try and execute a pdf report. now the following code i saved in a separate file in the website folder itself. and in the form that contains the print button, when clicked i want it to execute the code in the below mentioned code.
this is the function i used in the form. is this correct?
//print
function reportPrint(){
if(document.f1.pr.OnClick()){
$.get("http://localhost/drupal/pdf.php")
}
}please let me know if this is incorrect how to call the function from my form itself to execute another file with a script in the same folder
Hi friends,
I am back again with another very useful piece of code. MySQL has no easy report generation tool as
Oracle has, so its always developers who have to do this.
The following code helps you in developing reports for the MySQL Database.
The code has been tested by me and is working perfectly at
http:// galileo.tamucc.edu/~sri/PDF/pdfreportdemo.php
Please let me know if there is some problem with this code. I'll be glad to help you.
Please take care of the broken lines they mess your code a lot. If you indent them properly and run
the script with the few changes required to do, I am sure it would run perfectly.
Thank you,
Srikanth Turaga.
PSS: One of the members on the site has requested me to send some more stuff on PDF file generation
using FPDF. I didn't expect to come up with such a good code.
Finally thanks to Philip Clarke.
