Why Mysqli_stmt_bind_result Fails in Php?

phpaid · July 25, 2018, 11:37am

Php Gurus,

Now, I’m trying to write a php script that pulls matches from this mysql tbl.
The following url should have pulled that 3rd entry from my mysql tbl:
http://localhost/test/visitors_stats.php?visitor_type=unhappy_visitors&browsed_page_type=Information%20Page&browsed_page_url=http://7search.com/&links_per_page=25&page_number=

But it does not.
The page fails to pull the data. The page shows like this with hardly any data pulled:
"Search Result:
Visitor Type:
Browsed Page:
Browsed Page Type:
Matches: 0

0 Result Found …

Submission Date & Time in California Usa

Visitor Username:

Visitor Type:

Keywords Search:

Browsed Page:
trailers_stats.php?browsed_page=

Browsed Page Type:

Referral Page:
trailers_stats.php?referral_page="

Notice, the page shows “matches:0”. There should be a match on the 3rd entry (mysql tbl).
Anyway, here is my full code:

<?php 
 
//Required PHP Files. 
include 'config.php'; 
include 'header.php'; 
include 'account_header.php'; 
 
if (!$conn) 
{ 
$error = mysqli_connect_error(); 
$errno = mysqli_connect_errno(); 
print "$errno: $error\n"; 
exit(); 
} 
else 
{  
    //Get the Page Number. Default is 1 (First Page). 
$page_number = $_GET["page_number"]; 
if ($page_number == "") 
{ 
$page_number = 1; 
} 
 
$visitor_type = $_GET["visitor_type"]; 
$browsed_page_url = $_GET["browsed_page_url"]; 
$browsed_page_type = $_GET["browsed_page_type"]; 
 
echo "$visitor_type";//delete these as getting echoed
echo "$browsed_page_url";//delete these as getting echoed
echo "$browsed_page_type";//delete these as getting echoed
 
$links_per_page = $_GET["links_per_page"]; 
if ($links_per_page == "") 
{ 
$links_per_page = 25; 
} 
 
$max_result = 100;  
//$offset = ($page_number*$links_per_page)-$links_per_page; 
$offset = ($page_number-1)*$links_per_page; 
 
//$query_1 = "SELECT COUNT(*) FROM searching_histories WHERE visitor_type = ?"; 
$query_1 = "SELECT COUNT(*) FROM searching_histories WHERE visitor_type = ? AND browsed_page_url = ? AND browsed_page_type = ? ORDER BY id LIMIT ? OFFSET ?"; 
$stmt_1 = mysqli_prepare($conn,$query_1); 
//mysqli_stmt_bind_param($stmt_1,'sss',$visitor_type,$browsed_page_url,$browsed_page_type); 
mysqli_stmt_bind_param($stmt_1,'sssii',$visitor_type,$browsed_page_url,$browsed_page_type,$links_per_page,$offset); 
mysqli_stmt_execute($stmt_1); 
$result_1 = mysqli_stmt_bind_result($stmt_1,$matching_rows_count); 
mysqli_stmt_fetch($stmt_1); 
mysqli_stmt_free_result($stmt_1); 
 
$total_pages = ceil($matching_rows_count/$links_per_page); 
$query_2 = "SELECT id,date_and_time,visitor_username,visitor_type,searched_keywords,browsed_page_url,browsed_page_type,referral_page FROM searching_histories WHERE visitor_type = ? AND browsed_page_url = ? AND browsed_page_type = ? ORDER BY id LIMIT ? OFFSET ?"; 
$stmt_2 = mysqli_prepare($conn,$query_2); 
mysqli_stmt_bind_param($stmt_2,'sssii',$visitor_type,$browsed_page_url,$browsed_page_type,$links_per_page,$offset); 
mysqli_stmt_execute($stmt_2); 
$result_2 = mysqli_stmt_bind_result($stmt_2,$id,$date_and_time,$visitor_username,$visitor_type,$searched_keywords,$browsed_page_url,$browsed_page_type,$referral_page); 
mysqli_stmt_fetch($stmt_2); 
 
echo "$visitor_username";//WHY ARE NOT THESE GETTING ECHOED ?
echo "$visitor_type";//WHY ARE NOT THESE GETTING ECHOED ?
echo "$searched_keywords";//WHY ARE NOT THESE GETTING ECHOED ?

Solved the problem.

This url is now pulling the tbl data:

http://localhost/test/visitors_stats.php?visitor_type=unhappy%20visitor&browsed_page_type=Information%20Page&browsed_page_url=http://7search.com/&links_per_page=25&page_number=

The entry in mysql tbl was “unhappy visitor” and so I never should have added “unhappy_visitor” in the url.

Uniqueideman, yes, we know its you…

Because of your well established forum antics and attempts to hide your identity with numerous nicknames, you are not welcome on this forum. I have kept up on you and nothing has changed over several years.
