  1. 5.5 (i.e. 5:30) * 60 (minutes) * 60 (seconds) = 19800 I assume the 0 represent the first element of the array of timezone within the +5:30 UTC offset - 'Asia/Colombo'. Further, I expect you will ALWAYS get the first timezone corresponding to the UTC offset (as a default) because there is no way that an actual timezone can be specified in the string value you are using. '+05:30' => array ( 0 => 'Asia/Colombo', 1 => 'Asia/Kolkata', ),
  2. Look at the code examples on that page. The examples first create a datetime object with a specific timezone and then use gettimezone to retrieve the timezone that was previously set. A string such as "2021-05-06T13:48:19.2064951+05:30" has only the offset from UTC time - there is no timezone identifier. So, there is no way to programmatically determine the correct timezone out of the ones that share that offset.
  3. No clue. I think this is a JavaScript problem, not a PHP problem. I see the following code with references to "toggle" <a style="text-decoration: none;color: #000;" title="View Details" data-toggle="collapse" data-target="#products-details<?php echo $drow['order_id']; ?>"> <i class="nc-icon nc-minimal-down" onclick="changeToggleIcon(this)"></i> </a> But, those are tags within nothing in them to be displayed to the user. Further the actual javascript functions are not in the above code. If this is indeed a javascript problem, then you shoudl post the H
  4. Here is my suggestion: Limit the size of the images you will accept Do an initial check on the extension and MIME type of the file and refuse anything that is not what you expect Use getimagesize() to verify it is an image. Resize/recreate the image. This will remove some/most malicious code. Change the name of the image Set the folder(s) where you store the images so files cannot be executed Don't allow direct access to images. E.g. when displaying the images on a page use something like <image src="getimage.php?id=5"> and create the script geti
  5. No. There are lossless and lossy image compression formats. Both use different methods of storing the data. A RAW image format is one form of lossless image format that has distinct data for every single pixel along with it's color. That is why they are huge in storage space. A gif and jpg (typically) are lossy formats (substitute some fidelity to create small file sizes) but work very differently. A gif has a color palet that can only hold 256 colors. It then defines each pixel in the gif by those colors. I suspect it does some other calculations such as define the pixel at index 1, 1 then al
  6. Your table with events has a start and end date. How are you wanting the data displayed in the calendar - only an entry on the start date? Also, can there be multiple events on the same date? The answer to those questions will probably dictate how I would do it. I think the easiest approach would be to query all the events for the given month at the beginning of the function and put them into an array. Then when outputting the TD for any given day, check if there are any events for the day - if so, include them in the output. I thought your code was hard to read/work with, so I modified i
  7. I guess I'm still missing something. A user is on the "backoffice" page and they perform some action where you want to display a set of results in a new page "frontoffice" - is that correct? If the "frontoffice" page is opened from the "backoffice" page, then you can set a target on the "frontoffice" page. Then whenever the page is opened from "backoffice" it will replace the contents in the window that "frontoffice" was loaded in. FYI: You can use javascript in one window/tab to control another window/tab, but there has to be something to identify that other window/tab. It's typic
  8. Your question is unclear. Are these "pages" both currently open by the same user? I.e. the user clicks a button in one browser window that refreshes the content in another window? Or, is the page with a button something that User A clicks to initiate a refresh in a different page being viewed by User B? Better yet, why don't you explain the problem you are trying to solve that you think that creating such a scenario would solve? It's also important to know if these pages are hosted under the same domain. Do you have control over the content in both pages?
  9. You are using the "keys" from the user submitted data as the field names in your query! DO NOT DO THIS! Never trust the data from the user. Just because you provided the field names in the form does not mean that the user will submit that back. The user could arbitrarily send any field names or even malicious SQL code to expose or corrupt your DB.
  10. You are passing a string as the parameter for "jobTitle" <a href="Careers Results.php?jobTitle=Animator"> Then you are forcing that string to be an integer and comparing it to the original value (a string). A string and the integer value of a string will NEVER be the same. if( (int)$id == $id && (int)$id > 0 ) { Assuming your job titles have an ID (integer) and a Name (string value), you should craft your links to pass the ID as the parameter and not the Name. Use the Name as the text for the link: <a href="Careers Results.php?jobTitleId=5
  11. Your RegEx for email addresses is already flawed. Use built-in methods unless, as @gizmola stated, you have a use case that is not supported). As to your second question, if the error message you are referring to is one that is thrown from the DB, then you should absolutely have logic to show the message you define. Never expose DB errors to the user. You should always capture those and show a "friendly" message to the user that does not expose any details they could use to infiltrate the system.
  12. I think what you are after is having the course ID be the VALUE of the option (which is what is sent to the server) and the Course ID as the LABEL for the option. Also, only SELECT the field(s) you want in a query - do not use '*' $resultset = $conn->query("SELECT course_id, course_name FROM tbl_courses"); while($row = $resultset->fetch_assoc()) { echo "<option value='{$row['course_id']}'>{$row['course_name']}</option>"; }
  13. Not "horrible". There are use cases where that makes more sense than labels. E.g. when designing a form for a mobile device where screen real estate comes at a premium.
  14. For that matter, why have $obj2 at all! Just use $obj->Location where you want that value.
  15. Before you do that, you can verify if that is the problem. View the source of the page where the full name is not displayed and see if it is there in the content, but in such a way that it is malformed. You originally stated " . . . he is adding descriptions to the photos via a back end form, if he uses an apostrophe as in O'Sullivan for example, when he saves the entry, the description text does not show at all." First, I think it would be unlikely that output of the descriptions would be within an attribute. It might make sense if using the ALT attribute for an image, but that isn't nor
