Question

I am currently working on an CSV Uploader project and I have it working correctly but my question is – How would I make it select (firstname, lastname, email, phone, etc) if clients CSV file is put together differently. Or would the client who is uploading the file have to have it in the order the program is made?

Here is php code ———————————————-

try {  
  # MySQL with PDO_MYSQL  
  $DBH = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);  
  $DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

}  
catch(PDOException $e) { 
    echo "I'm sorry, I'm afraid I can't do that.";  
    file_put_contents('PDOErrors.txt', $e->getMessage(), FILE_APPEND);   
}

if (isset($_POST['submit'])){

    $file = $_FILES['files']['tmp_name'];   

    $handle = fopen($file , "r");

    while (($fileop = fgetcsv($handle,1000,",")) !== false)
    {
        $firstname = $fileop[0];
        $lastname = $fileop[1];
        $email = $fileop[2];
        $phone = $fileop[3];

        $insertdata = $DBH->prepare("INSERT INTO csv (firtname, lastname, email, phone) VALUES ('$firstname','$lastname','$email','$phone')");
        $insertdata->execute();
    }
    if ($insetdata){
        echo "Successfully Uploaded. Thank you.";   
    }
}

Thank you for your time!

New code

        file_put_contents('PDOErrors.txt', $e->getMessage(), FILE_APPEND);   
    }

    function returnBack(){

        header("Location:http://pcgprotects.com/PCG/csvuploader/csvuploaderform.php?seterror=1");
        exit;

    }

    if (isset($_POST['submit'])){

        /*******************************GET NAME OF COLUMNS IN CSV FILE *********************************************************/

In my csv trial file i used columns named – First name, Last name, Phone, Email. Then in my form I entered those values but I got kicked back – here is my Form code —–

    <table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form method="post" action="csvuploader.php" enctype="multipart/form-data">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>CSV Uploader </strong></td>
</tr>
<tr>
<td>Enter Name of First Name Column </td>
<td>:</td>
<td><input name="fisrtname" type="text" ><?php 
    $setError=$_GET['seterror']; 
    if($setError == 1){
    echo "<span class='errorMsg'>Need Exact Name</span>";
    }
        ?> </td>
</tr>
<tr>
<td>Enter Name of Last Name Column </td>
<td>:</td>
<td><input name="lastname" type="text" ><?php 
    $setError=$_GET['seterror']; 
    if($setError == 1){
    echo "<span class='errorMsg'>Need Exact Name</span>";
    }
        ?></td>
</tr>
<tr>
<td>Enter Name of Email Column </td>
<td>:</td>
<td><input name="email" type="text" ><?php 
    $setError=$_GET['seterror']; 
    if($setError == 1){
    echo "<span class='errorMsg'>Need Exact Name</span>";
    }
        ?></td>
</tr>
<tr>
<td>Enter Name of Phone Number Column </td>
<td>:</td>
<td><input name="phone" type="text" ><?php 
    $setError=$_GET['seterror']; 
    if($setError == 1){
    echo "<span class='errorMsg'>Need Exact Name</span>";
    }
        ?></td>
</tr>
<tr>
<td width="294"><input type="file" name="files" /><?php 
    $setError=$_GET['seterror']; 
    if($setError == 1){
    echo "<span class='errorMsg'>Select a File</span>";
    }
        ?></td>
</tr>
<br />
<tr>
<td><input type="submit" name="submit" value="Submit" /></td>

</form>

Answer 1

You can ask the customer to add one line in the beginning of the CSV that will show the structure, for example:

firstname,lastname,email,phone
joe,smith,[e-mail],41595648855
joe2,smith2,[e-mail],41595648852

…

from reading the first line – you’ll be able to know which token you should use with which index.

$file = $_FILES['files']['tmp_name'];   
$handle = fopen($file , "r");
$fileop = fgetcsv($handle,1000,",");
$firstname_index = array_search("firstname",$fileop);
$lastname_index = array_search("lastname",$fileop);
...
//and then
while (($fileop = fgetcsv($handle,1000,",")) !== false)
{
  $firstname = $fileop[$firstname_index];
  $lastname = $fileop[$lastname_index];
  ...
