Mmm.. you could make a image bigger with a simple javascript function.. var click = 0; function makeBigger(imgid) { var value=10; document.getElementById(imgid).width = document.getElementById(imgid).width +click*value; document.getElementById(imgid).width = document.getElementById(imgid).width + click*value; click++; } I think this will work, take a look here http://www.w3schools.com/htmldom/prop_img_height.asp http://www.w3schools.com/htmldom/prop_img_width.asp

You can use an onload event, check this pages http://www.w3schools.com/jsref/jsref_events.asp http://www.w3schools.com/JS/js_events.asp

Mmm.. well.. First of all var dest=document.getElementById(destination);, destination isn't declared in that function pass it as argument in the type function, function type(destination) { ... and when you call it destination=destinationParam; type(destination); , now you might want to call this function on a button click or something like that, if you want a button you could write something like this <input type="submit" value="Call Function" onclick="startTyping('text you want, if you want', 100, 'textDestination');">

Do you need this done after an event? I don't really know why is it looping, assign an event to call your function, it should be called once

Where's the loop there?

I wrote this function and it's not working, don't know why.. function valitadeForm(elementID) { var form = document.getElementByID(elementID); var isComplete = true; for(var i=0;i<form.lenght;i++) { if(form.element[i].name != "email") { if(form.element[i].value == null || "") { form.element[i].value = "Falta Rellenar Campo"; isComplete = false; } } else { var apos=form.element[i].value.indexOf("@"); var dotpos=form.element[i].value.lastIndexOf("."); if(apos <1 || dotpos-apos < 2) { form.element[i].value = "E-mail Incorrecto"; isComplete = false; } } } return isComplete; } I'm calling it like this <FORM id="addcomment" method="POST" enctype="application/x-www-form-urlencoded" action="?go=addcomment" onsubmit="return validateForm('addcomment')"> Any suggestions will be appreciated, thanks

Help needed to implement a simple AJAX thumb up/down voting script
Lautarox replied to seanmt's topic in Javascript Help
Take a look here http://www.w3schools.com/Ajax/ajax_intro.asp -
I have this php code with a form.. <?php echo'<html> <head> <script type="text/javascript" src="addform.js"></script> </head> <body>'; $album = $_GET['a']; $date = time(); $dia = date("j", $date); $mes = date("n", $date); $year = date("Y", $date); echo ' <table border=0> <div id="readroot" style="display: none"> <input type="hidden" name="album" value="'.$album.'"> <tr> <td><input type="button" value="Eliminar Ultima" onclick="this.parentNode.parentNode.removeChild(this.parentNode);"></td> </tr><tr> <td>Album ID: '.$album.'</td> </tr><tr> <td>Fecha:</td> <td><select name="day">'; for($i=1;$i<=31;$i++) { if($i == $dia) { echo '<option value="'.$i.'" selected="selected">'.$i.'</option>'; } else { echo '<option value="'.$i.'">'.$i.'</option>'; } } echo'</select>'; echo'<select name="month">'; for($i=1;$i<=12;$i++) { if($i == $mes) { echo '<option value="'.$i.'" selected="selected">'.$i.'</option>'; } else { echo '<option value="'.$i.'">'.$i.'</option>'; } } echo '</select>'; echo '<select name="year">'; for($i=$year;$i>$year-6;$i--) { if($i==$year) { echo '<option value="'.$i.'" selected="selected">'.$i.'</option>'; } else { echo '<option value="'.$i.'">'.$i.'</option>'; } } echo '</select> </td> </tr><tr> <td>Comentario o texto Adicional</tr> </tr><tr> <td><textarea rows="5" cols="26" name="text" maxlenght="250"></textarea></td> </tr> </div> <form name="photos" method="post" action="?go=10&d="> <span id="writeroot"></span> <tr> <input type="hidden" name="ammount" value="1"> <td><input type="button" id="moreFields" onclick="moreFields();" value="Mas Fotos"></td> <td><input type="submit" value="Subir Fotos"></td> </tr> </table> </form>'; echo' </body></html>'; ob_end_flush(); ?> And I have a javascript function to duplicate the form, I don't know really why isn't working, at the begining It wasn't even showing the form, so I added an ob_end_flush(), and now it adds the form, but incorrectly, not as the javascript function does. var counter = 0; function moreFields() { counter++; var newFields = document.getElementById('readroot').cloneNode(true); newFields.id = ''; newFields.style.display = 'block'; var newField = newFields.childNodes; for (var i=0;i<newField.length;i++) { var theName = newField[i].name if (theName) newField[i].name = theName + counter; } var insertHere = document.getElementById('writeroot'); insertHere.parentNode.insertBefore(newFields,insertHere); document.photos.ammount.value = counter; } window.onload = moreFields; Any suggestions? This is what's printing <div id="readroot" style="display: none;"> </div><div id="" style="display: block;"> -> it creates the div and it closes it </div><span id="writeroot"></span> -> it was supposed to write all the parts of the form before writeroot but instead it's only writing the div ¬¬ <table border="0"> <input name="album" value="12" type="hidden"> <tbody><tr> <td><input value="Eliminar Ultima" onclick="this.parentNode.parentNode.removeChild(this.parentNode);" type="button"></td> </tr><tr> <td>Album ID: 12</td> </tr><tr> <td>Fecha:</td> <td><select name="day">*select omitted * </select> </td> </tr><tr> <td>Comentario o texto Adicional</td></tr> <tr> <td><textarea rows="5" cols="26" name="text" maxlenght="250"></textarea></td> </tr> <form name="photos" method="post" action="?go=10&d="></form> <tr> <input name="ammount" value="1" type="hidden"> <td><input id="moreFields" onclick="moreFields();" value="Mas Fotos" type="button"></td> <td><input value="Subir Fotos" type="submit"></td> </tr> </tbody></table>

Please don't loose the thread, I the function is not returning the array that has the values for the pictures--
-
I discovered what the problem was, "if($size[1] > $thumb_width && $size[0] > $thumb_height && $size[0]/$size[1] > 1) {" I changed the positions of the $size's and now the thumbnail is created and the content is copied into the array, but is not passed in the return to the other function..
-
$foto and $thumbnail are values from the array returned from the function I pasted before, I'm still having problems creating the thumbnail and If I print the $content, that it's supposed to have some binary code, it doesn't have anything..
-
Well.. now I'm getting this Notice: Undefined variable: foto in /home/a4631774/public_html/class.php on line 1765 Notice: Undefined variable: thumbnail in /home/a4631774/public_html/class.php on line 1766 function addBikeCheck() { $photoarr = $this->photoProcess($_FILES['foto']['tmp_name'], $_FILES['foto']['type'], $_FILES['foto']['size'], $_FILES['foto']['name']); $photoarr[0] = $foto; -> first error $photorr[1] = $thumbnail; -> second error print($foto); print("mitad2 \n"); print($thumbnail); $bars = $_POST['bars']; $stem = $_POST['stem']; $grips = $_POST['grips']; $frame = $_POST['frame']; $cranks = $_POST['cranks']; $pedals = $_POST['pedals']; $seatpost = $_POST['seatpost']; $seat = $_POST['seat']; $fronthub = $_POST['fronthub']; $frontrim = $_POST['frontrim']; $fronttire = $_POST['fronttire']; $rearhub = $_POST['rearhub']; $rearrim = $_POST['rearrim']; $reartire = $_POST['reartire']; $fork = $_POST['fork']; $sprocket = $_POST['sprocket']; $rider = $_POST['rider']; $query = "INSERT INTO bikecheck (bars, stem, grips, frame, cranks, pedals, seatpost, seat, fronthub, frontrim, fronttire, rearhub, rearrim, reartire, fork, sprocket, rider, foto, thumbnail) VALUES ('$bars', '$stem', '$grips', '$frame', '$cranks', '$pedals', '$seatpost', '$seat', '$fronthub', '$frontrim', '$fronttire', '$rearhub', '$rearrim', '$reartire', '$fork', '$sprocket', '$rider', '$foto', '$thumbnail')"; parent::query($query); echo 'Bike Check Agregado Correctamente, <a href="?go=9&d=1">Volver</a>'; }

Why does it says this?

I'm sorry I missed the class part, I have it closed, I copied badly, the code is not working, that's the problem
-
First of all you must use a database to store all you need.. For getting the ammount of players, you can do a mysql_num_rows() with a select sentence to get the number of players. To get all the names and data of each player, you could select every player, and do a mysql_fetch_array(), about the pairing, you could create a table to store each game, the result and who played agains who, and with a select sentence you can get who played against someone and who didn't. I think you'll need to learn a little about php first

Well.. the problem was a bad located folder ¬¬, I fixed that, now I'm getting problems reading, creating the thumbnail and uploading both into the database.. Here's my actual code class bikecheck extends mysql{ function photoProcess($tmppath, $imgtype, $imgsize, $imgname) { $thumb_height = 150; $thumb_width = 233; if($imgtype == "image/jpeg" && $imgsize > 0 && $imgsize < 3145728) { $rand = rand(1, 400); $oldimgpath = "images/"."old".$rand.".jpg"; $newimgthumbpath = "images/"."thumb".$rand.".jpg"; if(!move_uploaded_file($tmppath, $oldimgpath)) { die("Errror moviendo file"); } if(!function_exists(imagecopyresampled) || !function_exists(ImageCreateTrueColor) || !function_exists(imagejpeg)) { die("Faltan funciones"); } $size = getimagesize($oldimgpath); if($size[0] > $thumb_width && $size[1] > $thumb_height && $size[1]/$size[0] > 1) { $destimgthumb = ImageCreateTrueColor($thumb_width,$thumb_height); $srcimg = ImageCreateFromJPEG($oldimgpath); imagecopyresampled($destimgthumb,$srcimg,0,0,0,0,$thumb_width,$thumb_height,ImageSX($srcimg),ImageSY($srcimg)); imagejpeg($destimgthumb,$newimgthumbpath,100); if($fp = fopen($oldimgpath, 'rb')) { $content = fread($fp, filesize($oldimgpath)); $content = addslashes($content); fclose($fp); print($content); } else { die("Error Abriendo Imagen en ".$oldimgpath.""); } if($fp = fopen($newimgthumbpath, 'rb')) { $content2 = fread($fp, filesize($newimgthumbpath)); $content2 = addslashes($content2); fclose($fp); } else { die("Error Abriendo Imagen en ".$newimgthumbpath.""); } $array[0] = $content; $array[1] = $content2; return $array; imagedestroy($destimgthumb); } } else { die("Fatal nigga"); } }

I'm getting this now.. Warning: move_uploaded_file() [function.move-uploaded-file]: open_basedir restriction in effect.

Do you mean something like this? $_SERVER['DOCUMENT_ROOT']."images/"."old".$rand.".jpg

I made this function to upload a image and it's thumbnail to a database and I'm getting an error while moving the image from the tmp folder, I have this code in a file called class.php and in the same dir, there's a folder called images.

I'm having some problems locating divs in a web page, I've an upper div, which I want it to be situated in the top, as a login bar, the problem here is that the bar sometimes is not perfectly aligned in the top without setting margin-top to -10px, and is not perfectly aligned also with the entire screen, I've used 100% as width, but some browsers with different resolutions doesn't seem to have problems with it, also the main problem why I'm asking is because I've setted all my divs as relative because the main div's size is continually changing, and I need to put a bar on the right of my main div, but the problem is that I can't get it in the place I want, I've declared it as absolute, and depending on the hight of the main div, it moves.. I'm using Firefox 3.05 Check it if you want.. http://201.231.17.94/apache2-default/carnet/ing/test/ Thanks in advance
