 I’ve just read several manual pages and forum comments on "Error number 1064" but I still don’t understand what’s going on with the problem I'm having now … Also, I'm surprised that the error message mentions two different line numbers (1 and 35).

  Here is the error message I get :  


And here are the contents of my "one_more_visit_to_topic.php" file :

I am a new developer, trying to figure out what causing a memory error. The code goes through registered appointments and depends on the service ID, I have to free a 45 minutes for another service to be booked. Now, once I book an appointment for any of the services that can have 45 minutes free spot, the website takes forever to load the hours but doesn't show them, instead I get this error

I'm getting this error for a blog script that is on my site :-

PHP Fatal error:  Uncaught TypeError: Unsupported operand types: string - int

 

The line in questions is this :-

$prev = $page - 1;

If I comment out this block of code the blog appears (with other errors, but I'll move on to those if I can fix this first!).

/* Setup page vars for display. */
    if (isset($page) and $page == 0) $page = 1;                    //if no page var is given, default to 1.
    $prev = $page - 1;                            //previous page is page - 1
    $next = $page + 1;                            //next page is page + 1
    $lastpage = ceil($total_pages/$limit);        //lastpage is = total pages / items per page, rounded up.
    $lpm1 = $lastpage - 1;                        //last page minus 1

 

Any idea's on what's needed to fix this script? I've contacted the original author but they haven't got back to me, I guess PHP8 maybe a little too new for them.

Thanks for any help....

I have a table with a list of users and an edit button and delete button.  When the edit button is pressed on a site it passes the user_id as p_id to the page that catches it and displays the data.  The problem is when I click on the "update user" button, I get the following error:

Warning: Undefined variable $the_user_id in C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php on line 10

Fatal error: Uncaught TypeError: mysqli_fetch_assoc(): Argument #1 ($result) must be of type mysqli_result, bool given in C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php:14 Stack trace: #0 C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php(14): mysqli_fetch_assoc(false) #1 {main} thrown in C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php on line 14

The weird thing is I had another update user page with a table I created that ran the query to update the table in the database just fine.  But as I created it, it didn't look all that great so I recreated the page and used a bootstrap table because of the much cleaner look.  Both pages have the exact same PHP code, the only difference is the bootstrap table I added in.  So I'm really at a loss with this.  Other than the table and PHP code, there is a script at the bottom of the page for the table itself to allow for searching within the table, i'll include that as well.  The PHP code is as follows:

<?php

//THE "p_id" IS BROUGHT OVER FROM THE EDIT BUTTON ON VIEW_ALL_USERS

if (isset($_GET['p_id'])) {

    $the_user_id = $_GET['p_id'];

}

// QUERY TO PULL THE SITE INFORMATION FROM THE p_id THAT WAS PULLED OVER

$query = "SELECT * FROM users WHERE user_id = $the_user_id ";

$select_user = mysqli_query($connection,$query);

//SET VALUES FROM ARRAY TO VARIABLES

while($row = mysqli_fetch_assoc($select_user)) {

    $user_id = $row['user_id'];

    $user_firstname = $row['user_firstname'];

    $user_lastname = $row['user_lastname'];

    $username = $row['username'];

    $user_email = $row['user_email'];

    $user_phone = $row['user_phone'];

    //$user_image = $row['user_image'];

    $user_title_id = $row['user_title_id'];

    $user_role_id = $row['user_role_id'];

   }

THE UPDATE QUERY CODE....................................................................................................................

<?php

if(isset($_POST['update_user'])) {

Hi there,
I have a local server set up on my computer which I have used before and it worked flawlessly. It is running apache with PHPand mySQL set up as services. Recently I attempted to copy a project I have worked on at school onto my server. I have the database up and running, however when I try to run a PHP file it gives me the error:
Quote

Fatal error: Cannot redeclare getText() in C:\Server\htdocs\projects\tournament\includes\functions.php on line 20

When I rename that function (which I know is not being redeclared) I get a browser error:
Quote

This webpage is not available.

The webpage at http://localhost/projects/tournament/index.php might be temporarily down or it may have moved permanently to a new web address.

  More information on this error
Below is the original error message

Error 101 (net::ERR_CONNECTION_RESET): Unknown error.


Has anybody else experienced this error and have a solution to fix it?
My guess is that it has to do with the function gettext() being available on this machine but not on the machine at school, however I thought PHP was case sensitive?
