PHP file upload with multiple post values - php

Question

I'm having a form that the user can fill in like this:
<form id="regForm" action="" method="POST">
<input type="text" name="name" class="form-control">
<input type="text" name="address" class="form-control">
<input type="text" name="city" class="form-control">
<input type="text" name="country" class="form-control">
<input type="file" name="callflowfile" class="form-control"> // the file
<input type="submit" name="formpost" class="form-control">
</form>
But when I post this form including the file, the file doesn't get uploaded and added to the DB.
This is my PHP code:
if(isset($_POST['formpost'])){
// insert name- address - city - county to DB
// insert callflowfile to directory
// If The array exists, add callflowfile
if ($_FILES["callflowfile"]["name"])
{
//Count number of files in array, loop through each file
for($i=0; $i<count($_FILES['callflowfile']['name']); $i++)
{
// If the file in array exists
if ($_FILES["callflowfile"]["name"][$i])
{
// If the file isnt 0 bytes
if ($_FILES["callflowfile"]["error"][$i] > 0)
{}
else
{
//move the file
// first get the original name of the uploaded file
$filename = $_FILES["callflowfile"]["name"][$i];
// now rename the original file into a random name
// get the file extension first
$ext = substr(strrchr($filename, "."), 1);
// then generate the random file name
$randomName = md5(rand() * time());
$filePath = "documents/" . $randomName . '.' . $ext;
// move the file and rename it
if(move_uploaded_file($_FILES["callflowfile"]["tmp_name"][$i], $filePath)){
// Add uploaded file row to database
}
}
}
}
}
}
The file isn't uploaded while the other form values are saved correctly.
I get the following error:
Undefined index: callflowfile in //directory
Does anyone know how to upload a file next to other form post values?

Answer 1

Add an enctype="multipart/form-data" attribute to your form so that it allows file(s) to be posted/uploaded :
<form id="regForm" action="" method="POST" enctype="multipart/form-data">
And you need to adjust file processing loop conditionals, change it like this :
if (isset($_POST['formpost'])) {
// insert name- address - city - county to DB
// insert callflowfile to directory
// If The array exists, add callflowfile
if ($_FILES["callflowfile"]["tmp_name"]) {
//Count number of files in array, loop through each file
for ($i = 0; $i < count($_FILES['callflowfile']['tmp_name']); $i++) {
...

replace your form tag by this
<form id="regForm" action="" method="POST" enctype="multipart/form-data">
And after update kindly do var_dump($_POST,$_FILES) at the first line of your php file you will get the all post fields within $_POST variable and Information of file will get in $_FILES
