PHP - File Upload "onchange" With Ajax
Hi. I have a page that allows users to upload some files, using <input type="file">...
What I would like is to be able to upload the file "onchange" of this input field using ajax so that (1) users can upload their second file while their first one is uploading, and (2) so that they can see their file on the page as soon as it's done uploading. But I can't seem to find a way to populate the $_FIlLES array without actually submitting the form. I've seen some stuff online where people use iframes to do this kind of thing, but I was hoping there was another way to do it. Any help would be great. Similar TutorialsCan someone please help me with an array problem i can not figure out. I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array. 1, "mysql_field_name", "Title of form field" 2, "", "" and so on then the form will be shown based on the array. I have the following draft code which I am working with. any suggestions on how i may do this array ? Code: [Select] <?php $options = array( '1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'), '2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'), '3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'), '4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'), ); // $options = array(1 => "option1", "option2", "option3", "option4"); // the line above works but i want to include the name of the mysql field as well. $userid = 1; ?> <div style="align: center; margin: 12px; font-family:Tahoma;"> <br><br><?php if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql. $res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'"); foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); } $ok_to_update = "no"; } elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data. // error checking // foreach($options as $key => $value) { // $_POST[$i] = ""; // } $ok_to_update = "yes"; } if ($_POST['Update'] == "Update" && $ok_to_update == "yes") { // $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database. ?><p><br><br><br>Thank you for updating</p><?php } else { ?><form name="form1" method="post" action=""> <?php foreach($options as $key => $value) { ?><p><?php echo($value); ?>: <input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p> <?php } ?> <input name="Update" type="submit" value="Update"> </form> <?php } ?> </div>

$.ajax({
url:'Ajax-PHP-Page.php?ProductNumber='+ProductNumber,
success: function(html) {
document.getElementById("my_div").value = '';

Thank you!! Edited May 5, 2020 by StevenOliverHi, bit stuck on how to find and replace "<" and ">" with "<" and ">". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once here's an example below Code: [Select] <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> the desired output would be: <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> help on this would be great Cheers Rob Hi guys I am a newbie with PHP and I have been trying to solve this problem for 3 days.. Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button.. The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears "Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27" When I check online I have this message "500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed." Are my codes wrong??? My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland Thanks for your help! Hi guys I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words. $find = "left"; $replace = array("up","down","forward","backwards"); $text = "left left left left"; echo str_replace($find,$replace,$text); The Output is: array array array array Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? Thanks I have been trying to replicate the facebook "share" functionality , well actually i was in need of this functionality even before i knew that fb already had it.. I learnt a few things that this can be achieved by using the "Curl" and I also hear that this setting may have been switched in some servers so if anyone can refer me to other options that would always fetch me the - Title- Description- Images for sure I' d be thankful Regards So I wanted to create stickers on my forum where people type in say ":Blobby-Tired" and then instead of the comment showing ":Blobby-Tired" it shows an html image tag displaying a picture of Blobby in the comment box So I created the following page CommentUpload.php However my sql fails to insert it despite the fact when I "echo $new" it shows the image on the page correctly And it can't be my sql insert code as if I change $new variable for "$BodyText" int he SQL query it it inserts ":Blobby-Tired" OK?
<?php
include 'dbconnect.php';
session_start();
if(isset($_POST["submit"]) && !empty($_POST["CommentText"])){
$id = intval($_SESSION['id']);
echo $_SESSION['id'] . '<p> </p>' ;
$BodyText = $conn -> real_escape_string($_POST['CommentText']) ;
$User = $_SESSION['username'];
//Replace flairs with <img> tags
/*not working currently) */
$new = str_replace(":Blobby-Tired","<img src='flairs/Blobby-Tired.jpg'> </img>","'$BodyText'");
echo "$new";
/************************/
$sql = "INSERT INTO Posts (User, CommentText, IdOfThread)
VALUES ('$User','$new','$id')";
if (mysqli_query($conn, $sql)) {
echo "New record has been added successfully !";
} else {
echo "Error: " . $sql . ":-" . mysqli_error($conn);
}

Edited April 28 by Fishcakes cant work out this mysql syntax error "operation":"medupdate","medid":"","name":"ibo","medyear":"5","medmonth":"21","medday":"1","recuser":1,"SuccFail":"fail","SuccFailMessage":"error occured You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '''WHERE med_id=' at line 2","ResultData":""} Code: [Select] $sql="update metodology set med_description='".$req['name']."', med_year='".$req['medyear']."', med_month='".$req['medmonth']."', med_day='".$req['medday']."', med_recorddate= now(), med_recorduserid= 1'"; $sql.= " WHERE med_id=".$req['medid']; I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? Just started. I am pretty sure composer.json wasn't changed. journalctl doesn't show anything. Maybe Doctrine related, however, nothing seems to help.
Any ideas?

HELP PLEASE! This topic has been moved to PHP Installation & Configuration. http://www.phpfreaks.com/forums/index.php?topic=347922.0 Hi, I currently have an if, elseif, else program that starts off with Code: [Select] if( $v_name == "" || $v_msg == "" ) echo "something" how do I turn this into a switch? but the very next elseif I have Code: [Select] elseif( strcspn( $_REQUEST['msg'], '0123456789' ) == strlen( $_REQUEST['msg'] ) ) echo "something" is it possible to turn this into a switch with 2 different strings like that to evaluate? When I Google the above string I find a lot of advice about using SFTP, turning on blocking, upgrading libraries and such, however, the code that does this seems to work during some operations and not work during others, so I don't think it's a matter of a buggy library. If I could find out why it cannot create the remote file, that might do a world of good. But I've been through all of /var/log and some log messages acknowledge the ssh session, but don't give any clues as to what goes wrong. I've looked at the user, password, host name and port name in and around the ssh2_connect() call. They are all good. I've also checked the permissions and ownership on the destination directory. They aren't the problem either. I've also tried duplicating the call w/a command-line scp call, and that test passes also. So now find myself staring at this "failure creating remote file" message, wondering what the failure is, and I'm running out of ideas. I'm running RHEL AS release 4.

I run a dev site locally on Windows and the real site on a hosting provider on LINUX. PHP5, XAMP, etc. Locally my fopen works. On the web server it throws an error: "Warning: fopen() [function.fopen]: Unable to access" filepath/name The file exists on both servers; upper/lower case is correct; so are access rights. I noticed the error only today; this was working for the last 7 months; the function serves a range of content-types; just tested XLS and it works. Now I am stuck This line throws the error: $handle = fopen($strPathFileName, 'rb'); $strPathFileName uses / only Any pointers appreciated... thanks. Hi all, I'm iterating 4 images out in a loop. All 4 images exist (definitely), and using an earlier script, have been resized to a width of 200px, so they are not large. I'm finding that if I use the following code: Code: [Select] $image_info = getimagesize($filename); $type = $image_info['mime']; echo $type; .. some of the images come up with no mime type. Is this normal? As a (possible) result of / link to having no mime type assigned to it, I'm getting: [function.getimagesize]: failed to open stream: No such file or directory .. but I am positive the image exists. Viewing the image info in a browser gives "image/jpeg", so I'm a bit weirded out as to how the script queries the image for a mime type, and it returns nothing. Has anybody else seen this, can anyone help? All the best, WoolyG I am creating a series of PHP scripts that allow for someone to append extra information to an Accident Claim Report. One of these scripts lists the files in a directory called the RCM directory. For the purpose of this, there is only one file in the list named "denman2.txt" and a hyperlink is attached to it so that the updated Accident Claim Report can be displayed. However, I would like it so that a style sheet could be applied to the "denman2.txt" text file, and I was wondering how it would be possible for the "denman2.txt" file to be opened in a format such as an HTML format so that a style sheet can be applied to it. Here is my Append Code: Code: [Select] <html> <head><title>Amend File</title></head> <?php if($_POST['append'] !=null) { $filename="C:/xampp/htdocs/rcm/denman2.txt"; $file=fopen($filename, "a"); $msg="Updated Information: " .$_POST['append']. "<br>"; fputs ($file, $msg); fclose($file); } ?> <body> <h1>Do you want to append to a document?</h1> Enter Updated Information: <form action="amendfile2.php" method="post"> <input type="text" size="40" name="append"><br><br> <input type="submit" value="Add updated information to report"> </form> <form action="viewfile3.php" method="post"> <input type="submit" value="View Web Blog"> </form> </body></html> My View File Code: Code: [Select] <html><head> <title>RCM File List</title></head> <body> <h1>Files in RCM Directory</h1> <?php $dir="C:/xampp/htdocs/rcm/*txt"; foreach(glob($dir) as $file) { $list = "<li><a href='readfile2.php'>Filename: $file</a></li>"; } ?> <ul> <?php echo $list; ?> </ul> </body> </html> And my Read File Code: Code: [Select] <html><head><title>Reading Accident Reports</title></head> <body> <?php function myErrorHandler($errno, $errstr) { echo "<b>Error: </b> [$errno] $errstr"; echo "<br>"; echo "End scripting"; die(); } set_error_handler("myErrorHandler"); $filename="C:/xampp/htdocs/rcm/denman2.txt"; $file = fopen($filename, "r"); while (!feof($file)) { $line=fgets($file,1024); echo "$line<br>"; } fclose($file); ?> </body> </html> Any help is appreciated Hi all, Using a form with check boxes divided into different categories, I collect data selected by the user. I now want to combine each choice in each category with each choice in the other categories and list the combinations to the user. If the user chooses one or more options in each category, it is relatively easy to nest foreach loops, since the number of categories will always be the same. For example, if the form contains three categories of options, the code will be: Code: [Select] foreach ($form['cat_1'] as $k1 => $val1) { foreach ($form['cat_2'] as $k2 => $val2) { foreach ($form['cat_3'] as $k3 => $val3) { echo $val1.' _ '.$val2.' _ '.$val3.'<br/>'; } } } Things get complicated if the user does not select options within a given category. More generally, I want to be able to generate the list regardless of the number of categories in which the user selects options. Thank you in advance for your advice. hello, I was wondering what is the point of writing for a dropdown: <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> or for a checkbox/ radio button: <?php if ($_POST['cb/radioID'] == "value") { echo "checked"; } ?> I guess it's for after submit, if there is any error, the values filled will still be echoed in the inputfield, or am i wrong? But then if that is true, i have a php search box where i use AJAX object to to send all the input they filled in after submit. But after pushing submit the inputted values remain. I guess when using AJAX to send the information i don't need <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> in my html forms? Little confused Can maybe somebody bring clearness |
