Displaying The Specific Uploaded Image On Student Home Page

Recommended Posts

Hello Admins and Php Freaks,

 

I have manage to upload the image using this codes

$student_id = $_POST['student_id'];
	$first_name = $_POST['first_name'];
	$last_name = $_POST['last_name'];
	$gender = $_POST['gender'];
	$date_of_birth = date("Y-m-d",strtotime($_POST['date_of_birth']));
	$contact_no = $_POST['contact_no'];
	$grade	= $_POST['grade'];
	$section = $_POST['section'];
	$LRN = $_POST['LRN'];
	$email1 = $_POST['email1'];
	$email2 = $_POST['email2'];
	$address = $_POST['address'];
	$description = $_POST['description'];
	$LRCardname= "";
	$LRCard2name= "";		
	
	
  	$query = "UPDATE student_information SET first_name='$first_name',last_name='$last_name',";    
    $query .= "gender='$gender',date_of_birth='$date_of_birth',contact_no='$contact_no',grade='$grade',section='$section',";
    $query .= "LRN='$LRN',email1='$email1',email2='$email2',address='$address',description='$description'";  	
	$query .= " WHERE student_id='$student_id'";      
	$result = mysql_query($query, $link_id);
	if(mysql_error() != null){
		die(mysql_error());
	}
		
	/*
			This block shows the start codes for the upload of the Learner Report Card.
	*/
	
	if($result){
			if($_FILES['LRCard']['name'] != ""){
				$filename = $_FILES['LRCard']['name'];
				$ext = strrchr($filename,".");
				$LRCardname = $student_id;
				$LRCardname .="_". $filename; 
				if($ext ==".jpg" || $ext ==".jpeg" || $ext ==".JPG" || $ext ==".JPEG" || $ext ==".gif" || $ext ==".GIF"){
					$size = $_FILES['LRCard']['size'];
					if($size > 0 && $size < 5000000){
						$archive_dir = "LRCards";
						$userfile_tmp_name = $_FILES['LRCard']['tmp_name'];
						if(move_uploaded_file($userfile_tmp_name, "$archive_dir/$LRCardname")){

What have you done so far?

The process should be pretty simple. On the page where you want the logo to appear, you need to get the image name for the image from the database, adding on whatever path you need in order for the image to link accurately ("path/to/image.jpg"), then, within the page, you add an image using a regular <img> tag, and insert the correct image path retrieved from the database using PHP.

This is so far what i got Ben and i failed to rename the uploaded file to its $student_id.

if($_FILES['image']['name'] != ""){
				$filename = $_FILES['image']['name'];
				$ext = strrchr($filename,".");
				$imagename = $student_id;
				$imagename .="_". $filename; 
				if($ext ==".jpg" || $ext ==".jpeg" || $ext ==".JPG" || $ext ==".JPEG" || $ext ==".gif" || $ext ==".GIF"){
					$size = $_FILES['image']['size'];
					if($size > 0 && $size < 1000000){
						$archive_dir = "images";
						$userfile_tmp_name = $_FILES['image']['tmp_name'];
						if(move_uploaded_file($userfile_tmp_name, "$archive_dir/$imagename")){

The file has been succesfully uploaded Ben but help me to insert the codes which to rename its file name to its student_id so i can display it to another page smoothly.

Sorry -- I haven't been around here much recently. I'm just about to move cross country (west coast USA to the east coast), so I've been pretty busy/preoccupied.

 

What does your current code do? Are you getting errors? Are you able to upload successfully? If so, what are the files named once the upload process completes?

Sorry to bother you Ben, There has been slightly changes since i am also working in solving the scenario. here is now my current codes.

if($_FILES['image']['name'] != ""){
				$filename = $_FILES['image']['name'];
				$ext = strrchr($filename,".");
				$imagename = $student_id;
				$imagename .="_". $filename; 
				if($ext ==".jpg" || $ext ==".jpeg" || $ext ==".JPG" || $ext ==".JPEG" || $ext ==".gif" || $ext ==".GIF"){
					$size = $_FILES['image']['size'];
					if($size > 0 && $size < 1000000){
						$archive_dir = "images";
						$userfile_tmp_name = $_FILES['image']['tmp_name'];
						if(move_uploaded_file($userfile_tmp_name, $archive_dir .'/'. $student_id .'_'. $imagename .'.'. $ext)){

this codes can upload an image.

there is no error.

the image is uploaded succesfully.

Example if the uplaoded file has a file name pic.jpg,,after it has been succesfully upload it is rename to

"_pic.jpg"

without the quotes just underscore and the file name itself.

What i wanted is to rename it to its unique student_id number so i can display it smoothly to another page.

This is the line that sets the final file name, which is currently the student id, and underscore, and the image name.

if(move_uploaded_file($userfile_tmp_name, $archive_dir .'/'. $student_id .'_'. $imagename .'.'. $ext)){

If you want to name the image just the student id, you would need to remove the 

'_'. $imagename .

portion. If the filename isn't being saved with the student id currently, you need to make sure that the $student_id value is set. Who is actually doing the uploading? The student themselves? An admin user? If it's the student themselves, do you set a session variable that holds their student ID when they log in? If so, you can set $student_id to the value of that session variable.

Yes Ben,

 

I understand your codes in fact that is what i am using. Actually, this is still on the process when the student register themselves-Registration_handler.php'. I suppose in this instance the student_id is not yet created.

 

This is the registration page where the student filled-up information including the uploading of their image.

OK. So if the user's ID isn't created yet, that's going to be the first step. You'll need to:

 

-- make sure that the user's information is completely valid

-- make sure the user's image is a valid type/size (assuming that the registration form includes both the user's information and an image upload

-- insert the user's information into the database

-- with the info inserted, use http://php.net/manual/en/mysqli.insert-id.php to get the last used id (the student's id)

-- upload the image

 

Personally, my suggestion would be to keep the registration process as short and as simple as possible, and save any non-essential information, such as a profile photo, for a "Edit Account" or "Edit Profile" page once they have logged in.

ok got it ben,,

 

i think i would accept your suggestion to keep registration process simple, that is always what im thinking all night long, thank you for confirming it. i'll work the codes now and put the adding of image on the Update profile.

 

Please stand by Ben, i may need your help after this ;-)

Hi Ben, 

 

i got new codes now that uploads the image of registered student with unique student_id. it is called Student_Edit_handler. This was in response to the idea you suggested.

$student_id = $_POST['student_id'];

i have writen flags on theStudent_Edit.php.

<?php  if(!empty($_GET['flag']) && $_GET['flag'] == "success") { ?>   
		<span class="stylered style1"><span class="style5">Learner Information updated successfully.</span></span>  
        <?php } else if(!empty($_GET['flag']) && $_GET['flag'] == "error") { ?>
		<span class="stylered style3 style5"><span class="style1">Error while updating Learner Information. Please try again</span></span> 
        <?php }  ?>	</td>

the specific error im getting is the flag=error which is 

"Error while updating Learner Information. Please try again."

The reason im pasting almost the whole codes.

When I look through your code, it looks like the only reason you are getting this error is if this returns false:

if($_FILES['image']['name'] != "")

So the next step would be to figure out if the $_FILES array is completely empty, and if so, resolve the error. This is a pretty good overview of the essentials regarding what is necessary in order to upload a file: http://www.w3schools.com/php/php_file_upload.asp

 

Are you sure you are using the proper 

enctype="multipart/form-data"

on your form? That is required to upload a file. Is your input for your file named correctly? For example, your input has to be named "image" in order for this to work properly.

These are my codes in the html

<tr class="stylesmall">
		  <td>Update Learner Image: </td>
		  <td colspan="3"><input type="file" name="image">
		           <span class="style3"> <span class="stylesmall">jpg or gif file only</span></span></td>
		</tr>
        <tr>
          <td colspan="4"><span class="stylered style6"><span class="style3">*</span> <em>fields are compulsory</em></span></td>
        </tr>
		
        <tr>
          <td colspan="4" align="center"><input name="update" type="submit" id="update" value="Update">

i read the link you gave me and tried to modify some codes but then it end up same error.

In that case, probably the best next step would be to change this section:

else{
    $flag="error";
}

Setting a flag doesn't help you. Instead, I would try doing a print_r() of the $_FILES array, to see what the array contains. Then continue debugging based on that.

Hello Ben, i have solved the flag part but still the problem of uploading image is there even i have followed your advise in enctype="multipart/form-data"

and these are the 3 warnings displayed except for being deprecated maybe you can figure this out.
