Warning: mysqli_query() expects parameter 1 to be mysqli, null given on line 43

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given on line 44

Warning: Cannot modify header information - headers already sent by (output started at:43) on line 87

Programmer: The-PC-Guy, Software Engineer replied 1 year ago

looking at the code it is this line

$row2 = mysqli_fetch_row(mysqli_query($con,'SHOW CREATE TABLE '.$table));

it should be

$row2 = mysqli_fetch_row(mysqli_query($link,'SHOW CREATE TABLE '.$table));

also this row

$result = mysqli_query($con,'SELECT * FROM '.$table);

same thing, $con needs to be $link

as far as the last error correcting the other 2 may fix that as well.

le me know the outcome

There are no additional php files needed. This link I provided is the only file that is being used to backup. The require at the top of the file is just verifying that the person is logged in but for the purpose of testing you can comment that line out. https://www.mediafire.com/?b21szssa716igba

I can't send the actual database but here are two test database. On has one table with data, the other has multiple tables but the tables are blank. let me know if this helps.

http://www.ge.tt/2bm7P3Z2

this should now be error free.

note the following:

1. since you are outputting file headers to the browser no html will be displayed, that includes text. This is normal behavior.

2. I set up output buffering in the script so ideally what you could do is assign the output text to a session variable or cookie, for displaying later. to the user, then add a redirect header, to send the user to another script that would output the file after the text was displayed in the previous script.

Everytime I try to download the file I am getting a warning that this file is unsafe to download and it is being blocked. What is the name of the file? Can you try uploading it again?

Programmer: The-PC-Guy, Software Engineer replied 1 year ago

I don't understand why you are giving me web pages. I just want my backup file to work.

Programmer: The-PC-Guy, Software Engineer replied 1 year ago

i modified your php code to work, so the file that I sent you is meant to replace your original.

I think you are sending me someone else file. When I download the zip file I am getting website pages for Winter in New York City. My php code has nothing to do with a website pages. I just trying to backup tables in a database using mysqli functions.

Programmer: The-PC-Guy, Software Engineer replied 1 year ago

Programmer: The-PC-Guy, Software Engineer replied 1 year ago

here I double checked the links, I posted the correct version of your file here, but for some reason it was not showing up. I did this several times now, I will try once more, hopefully this is your file.

Sorry for any confusion. This was beyond my control
