Get rid of NULL in excel export.

[Datnigz2002]

The below code works fine for me but I want to get rid of the word "Null" where cells are empty to clean up the spreadsheet. Any advice?

 

<?php
//EDIT YOUR MySQL Connection Info:
$DB_Server = "localhost";		//your MySQL Server 
$DB_Username = "phnxhelp";				 //your MySQL User Name 
$DB_Password = "password";				//your MySQL Password 
$DB_DBName = "phnx_help";				//your MySQL Database Name 
$DB_TBLName = "ticket_data";				//your MySQL Table Name 
//$DB_TBLName,  $DB_DBName, may also be commented out & passed to the browser
//as parameters in a query string, so that this code may be easily reused for
//any MySQL table or any MySQL database on your server

//DEFINE SQL QUERY:
//you can use just about ANY kind of select statement you want - 
//edit this to suit your needs!
$sql = "Select * from $DB_TBLName";

//Optional: print out title to top of Excel or Word file with Timestamp
//for when file was generated:
//set $Use_Titel = 1 to generate title, 0 not to use title
$Use_Title = 0;
//define date for title: EDIT this to create the time-format you need
$now_date = date('m-d-Y H:i');
//define title for .doc or .xls file: EDIT this if you want
$title = "Dump For Table $DB_TBLName from Database $DB_DBName on $now_date";
/*

Leave the connection info below as it is:
just edit the above.

(Editing of code past this point recommended only for advanced users.)
*/
//create MySQL connection

Can't you just use str_replace() like you did in other places in your script, to replace NULL with nothing ""?

[TEENFRONT]

if(!isset($row[$j]))
			$schema_insert .= "NULL".$sep;

 

 

Would ditching the word NULL not work?

[Datnigz2002]

Thank you that worked great! I snatched this off the net somewhere and just added my DB info. I have no idea what I'm doing just yet. Very new here.  Now how do I get it to only display certain tables?? The info being dumped is too much info...

[TEENFRONT]

$sql = "Select * from $DB_TBLName";

 

change the wildcard * to certain column names so...

 

$sql = "Select column1, column2, column3 from $DB_TBLName";

[Datnigz2002]

Wow thanks again!!

 

Also, if I can make it so I can change the name of the fields on the spreadsheet to something more friendly than the actual DB field names I'd like to know how I can go about doing that. Maybe even to change the names and automatically BOLD the fields in the spreadsheet??

[TEENFRONT]

u know whats spooky...

 

Iv been doing this for the past 2 days.. the EXACT same thing and i too are wanting to change the names and bold the titles. Just not got to that bit yet, so il let you know when i get there. If not, maybe someone else can help untill then?

[Datnigz2002]

Wow that is scary...

 

But you know I am not positive but I think I may have that at home. I remember doing it A LONG time ago. I'll search through my hard drives and if I find it I will post it.

 

Thanks!!!
