I have a form where user upload a excel file when click on upload submit button then file is move into folder but its cannot read records of each rows and columns in excel files. Here is form code

<form id="TypeValidation" method="" enctype="multipart/form-data">
    <div>
        <input type="file" name="donor_attachment" id="donor_attachment" />
        <button type="submit" name="donor_file" id="donor_file" value="donor_file" class="btn btn-success btn-round fileinput-exists">Upload</button>
    </div>
</form>

file is submit through ajax

$("#TypeValidation").on('submit',(function(e) 
 { 
  var fileUploadID = $(this).find('button[name="donor_file"]').val();
  e.preventDefault();   
   $.ajax({
        url: "fn_dsr_wizard_submit.php?submitid="+fileUploadID,
        type: "POST",
        data:  new FormData(this),
        contentType: false,
        cache: false,
        processData:false,
        dataType: "html",    
        success: function (result) { 
        alert(result);
        location.reload();
        if(result=='1'){
            location.replace("donors_dashboard.php");
        }else {
            location.replace("donors_dashboard.php");               
        }
        }
    }); 

    }

    ));

here is fn_dsr_wizard_sunbmit.php code

if(isset($_REQUEST['submitid']) && $_REQUEST['submitid']=='donor_file'){
global $con;

$userid = $_SESSION['Cont_ID'];
$company_id = $_SESSION['Company_ID'];

//Donor File Attachment
$F_filePath="../../uploads/ds_information/donor/";
$_FILES['donor_attachment']['name'];
if ($_FILES['donor_attachment']['name']!=""){
$donor_attachment = date('dmyhis')."_".$userid."_".$company_id."_".$_FILES['donor_attachment']['name'];
move_uploaded_file($_FILES['donor_attachment']['tmp_name'], $F_filePath.$donor_attachment);

$fileextension = explode(".",$donor_attachment);
if($fileextension[1]=="xls") {

$data = new Spreadsheet_Excel_Reader();
$html="<table border='1'>";
 for($i=0;$i<count($data->sheets);$i++) // Loop to get all sheets in a file.
  { 
    if(count($data->sheets[$i][cells])>0) // checking sheet not empty
     {
    for($j=1;$j<=count($data->sheets[$i][cells]);$j++) // loop used to get each row of the sheet
    { 
        $html.="<tr>";
        for($k=1;$k<=count($data->sheets[$i][cells][$j]);$k++) // This loop is created to get data in a table format.
        {
            $html.="<td>";
            $html.=$data->sheets[$i][cells][$j][$k];
            $html.="</td>";
        }
        $eid = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][1]);
        $name = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][2]);
        $email = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][3]);
        $dob = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][4]);
        //$query = "insert into excel(eid,name,email,dob) values('".$eid."','".$name."','".$email."','".$dob."')";

        //mysqli_query($connection,$query);
        $html.="</tr>";
    }
}

}

 $html.="</table>";
 echo $eid;
 echo $name;
 echo $email;
 echo $dob;
} 
}
else {$donor_attachment=$_SESSION['donor_attachment']; unset($_SESSION['donor_attachment']);}

if($_FILES['donor_attachment']['name'] !=''){
    $_SESSION['fileInsert']="donor_file_success_msg";
    echo 1;
}
else{
    $_SESSION['filenotInsert']="donor_file_error_msg";
    echo 0;
}

Answer 1

After I modified my code then read a records from excel file

if(isset($_REQUEST['submitid']) && $_REQUEST['submitid']=='donor_file'){
global $con;

$userid = $_SESSION['Cont_ID'];
$company_id = $_SESSION['Company_ID'];

//Donor File Attachment
$F_filePath="../../uploads/ds_information/donor/";
$_FILES['donor_attachment']['name'];
if ($_FILES['donor_attachment']['name']!=""){
$donor_attachment = date('dmyhis')."_".$userid."_".$company_id."_".$_FILES['donor_attachment']['name'];
move_uploaded_file($_FILES['donor_attachment']['tmp_name'], $F_filePath.$donor_attachment);

$filepath = "../../uploads/ds_information/donor/".$donor_attachment;
$fileextension = explode(".",$donor_attachment);
if($fileextension[1]=="xls") {

$data = new Spreadsheet_Excel_Reader();
$data->read($filepath);  
$html="<table border='1'>";
 for($i=0;$i<count($data->sheets);$i++) // Loop to get all sheets in a file.
  { 
    if(count($data->sheets[$i][cells])>0) // checking sheet not empty
  {
    for($j=3;$j<=count($data->sheets[$i][cells]);$j++) // loop used to get each row of the sheet
    { 
        $html.="<tr>";
        for($k=3;$k<=count($data->sheets[$i][cells][$j]);$k++) // This loop is created to get data in a table format.
        {
            $html.="<td>";
            $html.=$data->sheets[$i][cells][$j][$k];
            $html.="</td>";
        }
        $eid = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][1]);
        $name = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][2]);
        $email = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][3]);
        $dob = mysqli_real_escape_string($con,$data->sheets[$i][cells][$j][4]);
        //$query = "insert into excel(eid,name,email,dob) values('".$eid."','".$name."','".$email."','".$dob."')";

        //mysqli_query($connection,$query);
        $html.="</tr>";
    }
  }
 }

$html.="</table>";
echo $html;
 } 
}
 else {$donor_attachment=$_SESSION['donor_attachment']; unset($_SESSION['donor_attachment']);}

if($_FILES['donor_attachment']['name'] !=''){
    $_SESSION['fileInsert']="donor_file_success_msg";
    echo 1;
}
else{
    $_SESSION['filenotInsert']="donor_file_error_msg";
    echo 0;
}   
//}
}
