mysql_affected_rows() usage

[soycharliente]

Possibly a MySQL issue, but the function that is not behaving in the anticipated way is a PHP function.

 

Seems as though mysql_affected_rows() is not returning the desired number so I can move into my if statement.

 

This is just a snippet. Let me know if more code might be needed to diagnose.

<?php
dbconnect();
$sql = "INSERT INTO `registration` (`id`, `the_date`, `first_name`, `last_name`, `email`, `phone`, `street_address`, `city`, `state`, `zip`, `emergency_contact`, `emergency_phone`, `high_school`, `test_score`, `major_interest`, `gpa`, `activity1`, `activity2`, `activity3`, `activity4`, `recruitment`, `recruitment_explain`, `travel`, `language`, `language_years`, `rotc`, `interests`, `accommodations`, `pay`) VALUES (NULL, '{$the_date}', '{$first_name}', '{$last_name}', '{$email}', '{$phone}', '{$street_address}', '{$city}', '{$state}', '{$zip}', '{$emergency_contact}', '{$emergency_phone}', '{$high_school}', '{$test_score}', '{$major_interest}', '{$gpa}', '{$activity1}', '{$activity2}', '{$activity3}', '{$activity4}', '{$recruitment}', '{$recruitment_explain}', '{$travel}', '{$language}', '{$language_years}', '{$rotc}', '{$interests}', '{$accommodations}', 'N')";
$result = mysql_query($sql) OR DIE ('//INSERT error<br />Please report this to the site admin <a href="/contact/index.php">here</a>.<br /><br />'.mysql_error());
if (mysql_affected_rows($result)==1)
{
//send email
?>

I personally dont use mysql_affected_rows for single line INSERT queries..

 

I use:

if (mysql_query(...)) {
// success
} else {
//failure
}

or in your case

if ($result) {
//success
} else {
//failure
}

Works just how I wanted it to. Thanks.

 

What could be causing the function to not return the number of rows affected with a single line query?

The parameter that mysql_affected_rows() takes is a link identifier, not the value that mysql_query() returns.

 

The value returned by a INSERT/UPDATE/DELETE query is just a TRUE (the query executed without any errors) or FALSE (the query failed to execute because of an error, like a syntax error or a problem with the database) value anyway.

 

You can have a case (depends on the mysql server configuration or the use of the IGNORE keyword) where an INSERT query executes without error but the row will not be inserted.
