  1. Hi, Freaks, I hope all are well. I'm trying to make a while loop and there's a common manner used that I've seen in many, many example of code -> <?php while($row = mysqli_fetch_array($data_query)) { ... } and this manner of doing it auto-stops when it's to the end of the mysqli array. Using this exact way is not compatible with the syntax that I can use as I use a database wrapper that is highly abstracted. for example, this would be the typical layout of a DB query for a user post -> <?php $table = "un_posts"; $field = "deleted"; $value = "no"; $rule = "ORDER BY id DESC"; $query = $this->_db->get($table, array($field, "=", $value), $rule); $this->_data = $query->all(); // $this->_data is an array of objects and this would be my typical way of assigning the data -> <?php foreach ($this->data() as $obj) { $post_data = array( "id" => $obj->id, "content" => $obj->content, "added_by" => $obj->add_by, "date_added" => date("F d, Y H:i:s", strtotime($obj->date_added)), "user_to" => $obj->user_to, ); for project specific reasons I'd like to change this from a foreach loop to a while loop. What I found out is that the auto-stop of the while loop using the $row = mysqli..... does not work if I do something like this -> <?php while($obj = $this->data()) { $post_data = array( "id" => $obj->id, "content" => $obj->content, "added_by" => $obj->add_by, "date_added" => date("F d, 20y H:i:s", strtotime($obj->date_added)), "user_to" => $obj->user_to, ); and it creates an infinite loop. Keeping in mind that $this->data() (I have a class method data() that returns $this->_data if anyone noticed the difference) is an array of objects why am I not getting the same result as <?php while($row = mysqli_fetch_array($data_query)) { ... } I don't understand. They're both arrays being looped through. What's the difference where mine isn't breaking the loop at the end but the mysqli array breaks the loop at the end of it?
  2. Hi Freaks, the weekend is upon us again. I wish you all well. I have an issue I've been working on today and have hit a mental roadblock. Hoping someone with the time and will will talk me through it. I'm creating a table while looping through an API array and I've hit a couple snags. Here is the repeated HTML -> $html = " <tr class='mt-2'> <td>{$rank}.</td> <td><img src='{$image}' height='75' width='75'></td> <td>{$name}</td> <td class='bold'>\${$final_worth}B</td> <td class='{$class}'>\${$last_change}</td> <td>{$country}</td> <td>{$source}</td> <td><button class='bg-color-primary text-color-third px-2' id='more_btn' onclick='showDetails({$cnt})'>More</button></td> </tr> <tr > <div id='details'>lorem fucking ipsum wahoo baby</div> </tr> "; Everything was going as expected until I went to add the second row (div#details). There's actually 2 issues at play here - the first is how I make each button/div#details connected so button1 only effects div1 etc. I can't tackle that one yet though, because right now when any button is clicked div#details shows up above the table header rather than underneath the previous row. So until I have the positioning correct I can't really tackle the js functionality. Can someone please tell me why the <tr><div#details> is not appearing underneath it's previous row? The js code is as follows -> <script> var cnt = <?php echo $cnt; ?>; function showDetails(cnt) { var details = "details"; var x = document.getElementById(details); if (x.style.display === "none") { x.style.display = "block"; } else { x.style.display = "none"; } } </script> I know the code is a mess right now. It's kind of shameful lol but like I said I can't really do more with it until I can figure out why that table row isn't positioning properly
  3. I've made this code for a very simple registration form practice: //assign form variables $firstname = $_POST['firstname']; $lastname = $_POST['lastname']; $username = $_POST['username']; function clean_names($dirty_name) { strip_tags($dirty_name); str_replace(' ', '', $dirty_name); ucfirst(strtolower($dirty_name)); //return $dirty_name; } $names = array($firstname, $lastname, $username); if(isset($_POST['register_button'])) { // WHY IS THIS FUNC CALL NOT WORKING?? foreach($names as $name) { clean_names($name); } echo "First Name: " . $firstname . "<br>"; echo "Last Name: " . $lastname . "<br>"; echo "Username: " . $username . "<br>"; } The values are returned but they haven't been put through the clean_names function. I'm really new with PHP. Can someone tell me why this isn't working? Thank you
  4. So I have a database that is structured like this: https://imgur.com/a/DdyTqiE Sample data: https://imgur.com/a/kYwmuO1 For each appointment, a student can have multiple categories, such as 'Academic Probation, Re-Admit' etc... I would like to loop through this table, and get a count of how many were 'is_no_show' and 'is_cancelled' per (unique) category with respect to 'scheduled_student_services.' For example, in the sample data, we see that the first appointment has 4 categories (Academic Probation, Entering Cohort Year 20051, First Generation, and Re-Admit'). Now one of these categories - Academic Probation matches up with what they were scheduled for - '1st Term Probation Advising'. And they cancelled this appointment, so we want the count of cancellations under Academic Probation to go up by 1. How would I approach this? I know I probably need to do two loops but I'm not sure the PHP syntax for this. Any suggestions or tips would be helpful. Thank you for your time!
