  1. I have about 20 webpages that include mysqli procedural stuff, and I want to change those to mysqli procedural w/prepared statements. I've been through many sites that "teach" using prepared statements but none talk about converting an existing site to using them. An example (some of my existing code): if (isset($_POST['upload'])) { $description = $_POST['description']; $picAlt = $_POST['picAlt']; $status = $_POST['status']; mysqli_query($db, "INSERT INTO pics (fileName, description, picAlt, status) VALUES ('$fileName', '$description', '$picAlt', '$status')"); $_SESSION['message'] =
  2. I'm using the w3.css modal to display videos stored on the local server: <button onclick="document.getElementById('<?php echo $row['id']; ?>').style.display='block'" class="w3-button w3-black"><i class="far fa-play-circle fa-3x"></i> <?php echo $row['short_description']; ?></button> <div id="<?php echo $row['id']; ?>" class="modal"> <div class="modal-content"> <div class="w3-container"> <span onclick="document.getElementById(
  3. Oh, I just noticed something! The last "else" has no condition, is this the reason why my code didn't work? Because my final "else" had a condition? If true, then do I need to add a final "else" with no condition? (The page is working now without it.) But, what is the correct thing to do?
  4. Thanks, that does indeed fix it, but I don't understand why it is happening. After all, the form of the process is (from this W3 site) - if (condition) { code to be executed if this condition is true; } elseif (condition) { code to be executed if first condition is false and this condition is true; } else { code to be executed if all conditions are false; } Which is how my code was written, using the third condition as only "else".
  5. I am writing a CRUD and this is a test page to combine 3 separate files into one page. If I comment out the final "else" section entirely the first "if" section and the "else if" section work fine, no errors. After I remove the comment marks for the final "else" section I get this error: PHP Parse error: syntax error, unexpected '?>' in /public_html/crud/test.php on line 139 (<- the line 139 the error points to is the final php closing tag before the closing body tag) It should be obvious, simple, but I can't find any reason why it is throwing out that error and breaking the p
  6. I found my problem, and hopefully others searching these forums can learn from my mistake - I removed a level of div that was overriding a previously called div. The second div had display:block which was overriding the previous div which has display:table-cell. The two divs now match each others heights as described in the docs.
  7. Ok, I think I have something on this topic - the two cells do indeed always match sizes as long as the cell to the right is the same or small height as the cell on the left. If the right-cell is taller, the left-cell will not adjust and match the height. It appears to work only with the right-cell matching the left-cell. I haven't done any extra testing yet, but that appears to be what is happening. What I have done today is put some text in the left-cell and an image in the right-cell, if the image is taller than what the left-cell wants for the its own text, then the right-cell (image c
  8. FYI - (no help needed, this is a demonstration) - I'm in the process of developing a site for non-English speakers to learn conversational English (not grammar, as is the case with most English learning websites). While writing one of the pages I was experimenting with the radius and accordion and got some cool and unexpected results, you can see what I mean by looking at the page here - http://wiegand.org/ChipsEnglishHelp/a1-u0-intro.php Maybe some of you have already come across this, I don't know, but this is the first time I've seen this effect, anywhere. The accordion code I foun
  9. Here's the reference - https://www.w3schools.com/w3css/w3css_layout.asp Layout Cells Adjust to Equal Height Side-by-side w3-cell elements will also automatically self-adjust to equal height: I'm still having this problem, though it is not 100%, it might be more like 10%.

  11. I got it working, here's the code: <style> .menubar { width: 100%; clear:both; padding:.5em; box-shadow:0 .07em .07em black; background-color:yellow; border-left:.43em solid orange; border-radius:.57em; } .h1-bar a { color:#000; background-color:yellow; box-shadow:0 .15em .15em black, 0 0 1.8em orange, 0 0 .36em indigo; border-radius:.57em; padding:.5em; margin-top:.5em; } .bar { width:100%; overflow:hidden; display:inline-block; } .btnMenu { float:left; background: orange; padding:.15em; border-radius:.57em; margin-right:.75em; -webkit-transition: background-color .5s ease-o
  12. I have a menubar that works great in Opera 49.0 but in Firefox 57.0.2(64bit) and IE11 there are no links, therefore it doesn't work at all. If I move the link urls outside the buttons they work as expected, but the buttons are completely messed up. What could possibly be the problem? The html looks like this: <div class="w3-bar menubar "> <div class="h1-bar"> <button class="btnMenu"><a href="index.html">Home</a></button> <button class="btnMenu"><a href="courses.html">Courses</a></button> <
  13. hmm, yeah, those do not sound familiar at all, but for some reason, in the back of my mind, I just seem to recall seeing something about those two divs being automatically drawn to the same size without the use of tables. I don't like using tables for layout, they are for data.
  14. When making two side-by-side divs with different amounts of text in them, and coloring the background, the two divs are of different heights. Now, I can use the style/height to set a height in pixels for the two divs, but I seem to recall seeing something in the w3schools site that showed how to make the two divs automatically the same height without setting the height in pixels. Or am I mistaken?
  15. Yes I do, and that particular section will not change as it is for images/graphics that need a white background, rather than making all the images/graphics transparent. So for this site that is acceptable.
