  1. Hello. Stupid question here. So when i write sql code inside variable, do i need to change it (the variable) everytime or will php be able to see to difference?

  2. This script shows the fetched data in a modify form. In the old situation I used rec_num wich was corresponding to the record number in the database.table For security reasons I added a uniqid column to the table. So not like under with an input hidden attribute for uniqid. If possible I would like it to be stored in a session variable. This is doable like above, but outside the foreach loop only the last value is stored. How to connect every single uniqid value (for multiple records!) to the separated rec_num without users being able to see

  4. Hello, I've just read the tutorial on how to process a form in PHP, available on this site, and I was wondering if there's a specific reason to declare empty variables (or arrays) at the beginning? I don't understand what is the point of doing so. For example, in the following code, why would the 2sd and 3rd lines be necessary? <?php $errors = []; $name = $email = $message = ''; if (condition) { $errors['name'] = 'alert'; } else { $name = sanitize_input($_POST['name']); if (new_condition, $name) { $errors['name'] = 'new alert'; } }
  5. So my question is: how can I insert variables into my mysql queries in php?

  8. Hello, I've a problem when I try to send variables (django variables) from html to javascript. My variables contain coordinates, I mean, they are decimals, and when I receive them in the javascript and I show them in console, I've got only the no decimal part of the coordinates. This is my code: Template: <td><button onclick="window.to('{{p.coorx}}','{{p.coory}}')" data-coorx="{{p.coorx}}" data-coory="{{p.coory}}">Ver Pozo</button></td> Javascript: window.to = function(coorx,coory) { var coorx = parseFloat(coorx); var coory = parseFloat(coory); console.log(co
  9. Hi guys, I use a very big form and my variables will be saved in a session. In most cases I´m fine with PHP. Until now I just use JS to hide and show some options. My idea is to give the user a selection (somewhere in my form). As soon as the user clicks on one of the selection options, the value of the variable shall appear as text below the selection options (not just in the selection options). 1. Idea - import the php-variables in my JS and work with it <script type="text/javascript">var test ="<?php echo $test ?>";</script> --> didnt work. I could wo

  14. So I have a calendar that I created using JavaScript on an HTML page but now I need to create a variable that contains an array. The array needs to be a week long to-do list. Problem 1, I try to create the variable to produce the 'to-do' list but I'm not sure how to associate the array with a week out of the month. Second, I'm not sure where to plug in the variable once I have created it in order to make it show up in the calendar. Below is the script I wrote for the calendar. And help would be appreciated. Thanks! <!doctype html> <html> <head> <meta charset="UTF-8">
  15. I have a nifty query that pulls data by orders.orderid > '85000' (and I update that number every week based on orders.) But I want it to automatically pull the most recent 3,000 orders instead of changing that number all the time, so I was hoping to set a variable which is Max(order.orderid)-3000, thus pulling the last 3000 order records. Here is my static select: SELECT Orders.OrderID, Orders.OrderStatus, Orders.CustomerID, Orders.ShippingMethodID, Orders.BillingFirstName, Orders.BillingLastName, Orders.BillingAddress1, Orders.BillingAddress2, Orders.BillingCity, Orders.BillingState,

    [PHP] Problem

  18. Although I can console.log lastSel it is coming up as a blank when the PHP is called in the header. So when the header is passed it is id: "" even though clearly there is a value in lastSel and I am type casting to string. I am wondering what could be the source of the issue. lastSel is defined outside of any function braces as just "lastSel = """ without using the var keyword. Why would it be blank as String(lastSel) even though I can console.log a value? <script>$(function(){var date = new Date();var d = date.getDate();var m = date.getMonth();var y = date.getFullYear(); $('#cal
