PHP upload image

Question

Alright I have way to much time invested in this  I am new to PHP programming and trying to grasp the basics  but I am a little lost as of last night I was able to get a PHP form to upload basic data like a name address and stuff to my  MySQL  server   But today I said let s do the next step which would be an image to the server  I have watched 3 videos on YouTube probably a 100 times just recoping code and trying it in so many different ways   http   www youtube com watch v CxY3FR9doHI http   www youtube com watch v vFZfJZ WNC4 amp feature relmfu   and still haven t been able to get it    But long story short  I have a config php file that connects to the server and here is the the code I m running on the upload form page    lt html gt     lt head gt       lt title gt Upload an image lt  title gt     lt  head gt   lt body gt     lt form action  UploadContent php  method  POST  enctype  multipart form-data  gt    File       lt input type  file  name  image  gt   lt input type  submit  value  Upload  gt     lt  form gt   lt  php     connect to database include config php       file properties  file     FILES  image    tmp name     if   isset  file     echo  Please select a profile pic   else      image   addslashes file get content   FILES  image    tmp name         image name   addslashes  FILES  image    name        image size   getimagesize   FILES  image    tmp name        if   image size  FALSE      echo  That isn t a image      else          insert   mysql query  INSERT INTO content VALUES                               image name    image               gt     lt  body gt   lt  html gt    The reason for all the                on the insert line is because I have the name in the 10th field and the image blob in the 11th and all the ones leading up to that are first name  last name and random stuff like that  How can I fix this  It is returning the error      Fatal error  Call to undefined function file get content   in  home content 34 9587634 html WEBPAGE UploadContent php on line 22   I don t know what to do

This code is very easy to upload file by php  In this code I am performing uploading task in same page that mean our html and php both code resides in the same file  This code generates new name of image name   first of all see the html code   lt form action  index php  method  post  enctype  multipart form-data  gt    lt input type  file  name  banner image   gt    lt input type  submit  value  submit  gt    lt  form gt    now see the php code   lt  php  image name   FILES  banner image    name            temp   explode       image name            newfilename   round microtime true           end  temp           imagepath  uploads    newfilename         move uploaded file   FILES  banner image    tmp name    imagepath     gt

The code overlooks calling the function move uploaded file   which would check whether the indicated file is valid for uploading   You may wish to review a simple example at   http   www w3schools com php php file upload asp

Change function file get content   in your code to file get contents     You are missing  s  at the end of function name  That is why it is giving undefined function error   file get contents    Remove last unnecessary comma after  image filed in line   INSERT INTO content VALUES                                       image name    image

Here is a basic example of how an image file with certain restrictions  listed below  can be uploaded to the server    Existence of the image   Image extension validation   Checks for image size    lt  php     newfilename    newfilename       if isset   FILES  image             errors  array           file name     FILES  image    name           file size    FILES  image    size           file tmp    FILES  image    tmp name           file type   FILES  image    type           file ext strtolower end explode       FILES  image    name               expensions  array  jpeg   jpg   png          if file exists  file name             echo  Sorry  file already exists                    if in array  file ext  expensions     false             errors    extension not allowed  please choose a JPEG or PNG file                   if  file size  gt  2097152             errors    File size must be excately 2 MB                  if empty  errors   true           move uploaded file  file tmp  images    newfilename      file ext           echo  Success           echo   lt script gt window close    lt  script gt                    else           print r  errors                  gt   lt html gt      lt body gt          lt form action    method  POST  enctype  multipart form-data  gt            lt input type  file  name  image    gt            lt input type  submit   gt         lt  form gt       lt  body gt   lt  html gt    Credit to this page

I would recommend you to save the image in the server  and then save the URL in MYSQL database    First of all  you should do more validation on your image  before non-validated files can lead to huge security risks    Check the image  if  empty   FILES  image       throw new Exception  Image file is missing     Save the image in a variable   image     FILES  image     Check the upload time errors  if   image  error       0       if   image  error       1         throw new Exception  Max upload size exceeded        throw new Exception  Image uploading error  INI Error       Check whether the uploaded file exists in the server  if   file exists  image  tmp name         throw new Exception  Image file is missing in the server     Validate the file size  Change it according to your needs     maxFileSize   2   10e6       2 000 000 bytes   2MB     if   image  size    gt   maxFileSize          throw new Exception  Max size limit exceeded      Validate the image  Check whether the file is an image     imageData   getimagesize  image  tmp name          if    imageData        throw new Exception  Invalid image     Validate the image mime type  Do this according to your needs     mimeType    imageData  mime      allowedMimeTypes     image jpeg    image png    image gif     if   in array  mimeType   allowedMimeTypes        throw new Exception  Only JPEG  PNG and GIFs are allowed       This might help you to create a secure image uploading script with PHP   Code source  https   developer hyvor com php image-upload-ajax-php-mysql  Additionally  I suggest you use MYSQLI prepared statements for queries to improve security    Thank you
