 | Hi! In addition to Dave's suggestion, having a div between rows is not really correct: <table> <tr> <td> <div class="img"> <tr> <td><img src="..." /> </div> <tr> <td> </table> Do: <table> <tr> <td> <tr> <td><div class="img"><img src="..." /></div> <tr> <td> </table> Or simply: <table> <tr> <td> <tr> <td><img class="img" src="..." /> … |
| | It happens because you're missing the quote for the previous values, this: ('60', 'Ng'wagindu), should be: ('60', 'Ng'wagindu'), |
| | Re: Php simple error **@phoenix** There are some errors here: echo work $sql ="UPDATE tea SET name = ' 8req' WHERE id = '3 ' "or die ("cant update" . mysql_error()); The echo statement needs quotes if you're trying to return a string, if that is a constant it's ok, but you have to … |
 | Re: diff in arrays Hi, the function `array_diff()` will return empty: 1. if the first array is smaller then the second; 2. and if the elements in the first array range are the same of the second. For example: $a = [1,2]; $b = [1,2,3]; print_r(array_diff($a, $b); Will return empty, instead: $a = [1,2]; …  |
| | Re: null2unknown Hi, the function `null2unknown()` is not a PHP function, it's a **user defined function** so there must be a file, included by payment_gateway.php or by a main file, which defines the above function. The GET variables, instead are usually set by form fields: <form method="get"> <input type="text" name="vpc_Amount"> ... </form> … |
 | Hi! The problem is caused by the quotes, you need to escape them correctly, try: $pm_ui = '<button id="pmBtn" onclick="postPm(''.$u.'',''.$log_username.'','pmsubject','pmtext')">Send</button>'; In your case you're including PHP variables and your using single quotes, so you have to escape those to create the javascript arguments, and make the variables print their values. … |
 | Hi there, @Dave consider that points generated in March and April 2015 (in the range of 45 days if I'm not mistaken) are only estimated points and need to be reviewed by the team, those months are marked by an asterisk. I think there is a thread in which Dani … |
| | Re: File upload Don't rely on the value returned by the $_FILES array because is set by the client, which can be altered or simply different from what expected. For example some executives will return `application/x-dosexec`. Use the **finfo** library: $finfo = new finfo(FILEINFO_MIME_TYPE); $type = $finfo->file($file); if(in_array($type, array('mime', 'blacklist'))) { # ... … |
| | Hi! Change also the value of `post_max_size`, this should be equal or larger than `upload_max_filesize`. Docs: http://php.net/manual/en/ini.core.php#ini.post-max-size |
 | Hi, the code seems fine to me. But you can try this function which extends a bit the check: function get_ip_address() { $array = array( 'HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR' ); foreach($array as $key) if(array_key_exists($key, $_SERVER) === true) foreach(explode(',', $_SERVER[$key]) as $ip) if(filter_var($ip, FILTER_VALIDATE_IP) !== false) return $ip; … |
| | Hi, `getimagesize()` is a function to evaluate the pixels of an image, the type and the attibutes (a stringed version of height and width), it returns an array. For example: Array ( [0] => 20 [1] => 10 [2] => 2 [3] => width="20" height="10" [bits] => 8 [channels] => … |
| | Hi, it seems fine to me, but you can use directly the object created by the `diff()` method, without formatting the output, as [in my previous example](https://www.daniweb.com/web-development/php/threads/493999/how-to-get-differenc-in-hours-and-minutes-#post2160993): $minutes = 0; $minutes += $diff->h * 60; $minutes += $diff->i; echo round($minutes / 4); Which outputs `23`, with floor `22`. If you … |
 | Hi, if you're using a prepared statement to insert the data, then submit the zipcode as a string, not as integer, this should solve the issue for you. The table column must be char or varchar, as you're already doing. |
| | Hi, use the DateTime library, in particular look at the `diff()` method. For example: <?php $one = '09:30AM'; $two = '06:30PM'; $dtime_1 = new Datetime($one); $dtime_2 = new Datetime($two); $diff = $dtime_1->diff($dtime_2); echo $diff->format('%H:%I'); Will print `09:00`.

I ask this because the function that checks the path is this: // Since 2.0: security reason function check_direct_including($incln) { global $PHP_SELF; $Uri = '//'.dirname( $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] ); if (strpos(getoption('http_script_dir'), $Uri) !== false && strpos($PHP_SELF, $incln) !== false) die(proc_tpl('help/manual/wrong_include', array('category' … |
 | Hi, you need at least MySQL 5.1.5 to import XML, otherwise you have to check if a UDF (user defined function) was developed to support old versions. In the documentation you can find a comment (bottom of the page) that suggests a workaround, sincerly I wouldn't use it. If possible … |

| | Hi, it could be the mime-type or the column table size, be sure to not truncate the input. If using a `blob` column type then this can support up to 65536 bytes. To save more data use `mediumblob` which supports up to 16MB or `longblob` which supports up to 4GB. … |
 | Re: CI CRUD - routes If you write: onClick="parent.location='cadd_latihan/'" your link is relative to the page in which this is clicked, so if you open it in `/home/` the client asks for `/home/cadd_latihan/`, if you click it in `/contact/` the client asks for `/contact/cadd_latihan/`. To fix it, add a leading slash to the url and … |
| | Hi, you actually get the result, just loop it: $result = $pdo->query("SELECT * FROM posts"); foreach ($result as $key => $value) echo $value['title']; echo 'Total: '. $result->rowCount(); It's not visible through `print_r()` because the statement is an iterable object, if you want the full array use `fetchAll()`: print_r($result->fetchAll()); As second … |
| | Hi, use `trim()` to remove the pending comma: echo trim('a,b,c,', ','); The same can be done at query level: select trim(TRAILING ',' FROM 'a,b,c,'); Docs: * http://php.net/trim * http://dev.mysql.com/doc/refman/5.6/en/string-functions.html#function_trim |
 | > the form gets posted it will only return the first variable that i place in the paranthesis like It happens because the `message()` method takes only one argument. In order to work correctly you should write something like this: $this->email->from('contact@domain.tld', 'From WebSite'); $this->email->reply_to($email, $name); $this->email->to('me@domain.tld'); $this->email->subject('Message from contact form'); … |

| | Re: Cron Job You can remove `/usr/bin`. When not sure about the path of a command you can use `env`, e.g.: /usr/bin/env php script.php --attribute hello --import ../world.txt but not in case of `cd`, you don't need it. In any case I'm not sure the above script will work, because the `--file` attribute … |
| | **@k_manimuthu** Hi, the `FROM` statement is not allowed in the update query, this is reason you get the error. This will work: UPDATE tb2,tb1 SET tb2.data = tb1.data WHERE tb1.id = tb2.id AND tb2.data IS NULL; Which is almost the same of your previous query with Reverend Jim fix to … |
| | It seems all these arrays will have the same size, so you can loop them together, for example: # read size of one of these arrays $count = count($_REQUEST['gender']); # loop for($i = 0, $e = 1; $i < $count; $i++, $e++) { echo "Student #{$e}: Gender: $gender[$i] / Shoe-Size: … |

| | I don't know if there is a ready PHP solution for this, but if you can install software in your hosting, then use LibreOffice in command line mode: <?php $file = 'something.doc'; $str = sprintf("libreoffice --headless --invisible --convert-to pdf %s", $file); $cmd = escapeshellcmd($str); exec($cmd); There are other solutions as … |
| | Hi, regarding the ffmpeg execution in `$RF->newname` are you returning only the filename or also the path in which this file is located? Is the destination path writable? Regarding the execution of the controller from CLI, it seems you are autoloading the session library, this will give the kind of … |
 | Also explain the reason, because you could simply use the [Alias directive](http://httpd.apache.org/docs/2.4/mod/mod_alias.html) to point the external directory to clients: Alias /uploads /etc/mnt/storage/uploads that way you don't have to alter your scripts, but if your boss decision was taken for security reasons, then Alias is the wrong solution. |
| | Hi, maybe you have multiple file type fields in your page? Try by identifying the field by the ID attribute, for example: // by default, submit is disabled $("#submit").attr("disabled", "true"); $("#upload").on('change', function(){ var val = $(this).val().toLowerCase(); if(!val) { alert('upload your photo'); $(this).focus(); $("#submit").attr("disabled", "true"); return false; } else { var … |

| | The function `array_walk_recursive` will set the index key as second argument of the mapped function, the third argument will be the third of the function, since `ltrim` takes only two arguments it's better to define a custom function.
