  • Incrementing through mysql PHP

    - by Rawdon
    I am looking at try to increment and decrement by three records through a table and present those records. Say if the id '4' is currently active. I want the to be display the ID's and category of 3.2.1 and 5.6.7 from an increment and decrement So far I have: $stmt = $db->query("SELECT id, category FROM test"); $stmt->execute(); while ($results = $stmt->fetch(PDO::FETCH_ASSOC)) { $current = $results['id']; $category = $results['category']; $next = array(array('slide_no' => $current, 'category' => $category)); } print_r($next); Now with this, I am getting back every row in the table. I'm now getting confused on how I could increment and decrement the records by 3 and make sure that the category will also increment correctly. Thank you very much.

  • PHP Put list from Powershell into Array

    - by Mezzan
    Code: $exchangesnapin = "Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010"; $output = shell_exec('powershell '.$exchangesnapin.';"get-mailboxdatabase" 2>&1'); echo( '<pre>' ); echo( $output ); echo( '</pre>' ); Result: Name Server Recovery ReplicationType ---- ------ -------- --------------- Mailbox Database 0651932265 EGCVMADTEST False None Mailbox Database 0651932266 EGCVMADTEST False None I tried with echo( $output[1] ); The result was only a letter 'N'. I believe its taking the Name column but one character at a time. $output[1] is 'N', $output[2] is 'a'. Is there any way I can get the mailbox list into array?

  • Thumbnailing and then Saving as a Blob with PHP in Wordpress

    - by Parris
    The below code seems like it should work; however, the blob in the database only contains 0 after the function is run. Does the below code look accurate? If not how can I fix it? $tmpName = $_FILES['picture']['tmp_name']; $fp = fopen($tmpName, 'r'); $binary = fread($fp, filesize($tmpName)); fclose($fp); $originalImage = imagecreatefromstring($binary); $tempImage = imagecreate(100,100); imagecopyresized($tempImage,$originalImage,0,0,0,0,100,100); ob_start(); imageJPEG($tempImage); $thumbnail = ob_get_contents(); ob_end_clean(); $wpdb->query("UPDATE ".$wpdb->prefix."items SET picture = $thumbnail WHERE id=$id'"); Thank :)!

  • Php, in_array with no exactly match

    - by John Smith
    I want to do the following: $a = array(); $a[] = array(1,2); $a[] = array(2,5); $a[] = array(3,4); var_dump (in_array(array(2,5), $a)); this returns OK, as it expected, but if the source array is not fully matched: $a = array(); $a[] = array(1,2, 'f' => array()); $a[] = array(2,5, 'f' => array()); $a[] = array(3,4, 'f' => array()); var_dump (in_array(array(2,5), $a)); it returns false. Is there a way to do it with the built-in way, or I have to code it?

  • PHP: reusing database class

    - by citricsquid
    Hi, I built a class that allows me to do: $db->query($query); and it works perfectly, although if I want to do: $db->query($query); while($row = $db->fetch_assoc()){ $db->query($anotherquery); echo $db->result(); } it "breaks" the class. I don't want to constantly have to redeclare my class (eg: $seconddb = new database()), is there a way to get around this? I want to be able to reuse $db within $db, without overwriting the "outside" db. currently I'm create an array of data (from db-fetch_assoc() then doing a foreach and then doing the db call inside that: $db->query('SELECT * FROM table'); while($row = $db->fetch_assoc()){ $arr[] = $row; } foreach($arr as $a){ $db->query(); // query and processing here } Is this the best method or am I missing the obvious? Should I consider passing a connection link ID with the database connection?

  • PHP: Prevent a function from returning value?

    - by Industrial
    Hi everybody, How could I make sure that the startProcess(); function is being called, but without halting the execution for myFunction().

Pseudo-code: function myFunction() { startProcess(); return $something; } function startProcess() { sleep(5); // Do stuff that user doesn't should have to wait for. }

  • PHP parameter without value using for navigation

    - by somewalri
    Hello, I am trying to set up a navigation system that uses GET parameters with no value, example: http://foo.bar/?mainPage takes the visitor to the main page. So I am using if statements and I am wondering if there is a way I can do this without a bunch of if statements? I don't think switch statements would work for this. This is currently what I have: $mainPage = $_GET['mainPage']; $contact = $_GET['contact']; if(isset($mainPage)) { // go to main page } if(isset($contact)) { // go to contact page } I don't want to have to end up writing a ton of if statements, though. Any ideas? Thanks.
