updating file

   <?php include "config.php"; if(isset($_post['submit']))   {      $target = "images/".basename($_files['image']['name']);    $v_type = $_post["v_type"];    $v_name = $_post["v_name"];    $v_man = $_post["v_man"];    $v_model = $_post["v_model"];    $v_color = $_post["v_color"];    $v_trans = $_post["v_trans"];    $v_1_15_rent = $_post["v_1_15_rent"];    $v_16_25_rent = $_post["v_16_25_rent"];    $v_25_plus_rent = $_post["v_25_plus_rent"];    $v_reg = $_post["v_reg"];    $vendor_name = $_post["vendor_name"];    $vendor_mobile = $_post["vendor_mobile"];    $vendor_price = $_post["vendor_price"];    $image = $_files["image"]["name"];    $v_id=$_get["v_id"];     $sql = " update my_veh_ven set v_type='$v_type', v_name='$v_name' ,v_man='$v_man' ,v_color='$v_color', v_trans='$v_trans',  v_1_15_rent='$v_1_15_rent' , v_16_25_rent='$v_16_25_rent' ,v_25_plus_rent='$v_25_plus_rent' , image='$image' , v_reg='$v_reg' ,vendor_name='$vendor_name', vendor_mobile='$vendor_mobile' ,vendor_price='$vendor_price'  v_id='$v_id' ";    if (mysqli_query($conn, $sql))      {          if(move_uploaded_file($_files['image']['tmp_name'], $target))                 {                 $success = "✓ updated";                 }     }   else    {                 $fail = "x  not updated";    }    }      mysqli_close($conn);   ?> 

an <input type="file"/> has no value attribute usage. image, once uploaded, on server , that's it. cannot set value of input meaningful.

what want display uploaded picture instead of input, , present input if user wants change it.

edit: have php code, can see overwriting $image variable if empty

$image = $_files["image"]["name"]; 

you have verify if $_files["image"] exists, else image null or undefined. , update database bad value. suggest treat upload differently other data:

<?php include "config.php"; if(isset($_post['submit']))   {      $target = "images/".basename($_files['image']['name']);    $v_type = $_post["v_type"];    $v_name = $_post["v_name"];    $v_man = $_post["v_man"];    $v_model = $_post["v_model"];    $v_color = $_post["v_color"];    $v_trans = $_post["v_trans"];    $v_1_15_rent = $_post["v_1_15_rent"];    $v_16_25_rent = $_post["v_16_25_rent"];    $v_25_plus_rent = $_post["v_25_plus_rent"];    $v_reg = $_post["v_reg"];    $vendor_name = $_post["vendor_name"];    $vendor_mobile = $_post["vendor_mobile"];    $vendor_price = $_post["vendor_price"];     $v_id=$_get["v_id"];     $sql = " update my_veh_ven set v_type='$v_type', v_name='$v_name' ,v_man='$v_man' ,v_color='$v_color', v_trans='$v_trans',  v_1_15_rent='$v_1_15_rent' , v_16_25_rent='$v_16_25_rent' ,v_25_plus_rent='$v_25_plus_rent' , v_reg='$v_reg' ,vendor_name='$vendor_name', vendor_mobile='$vendor_mobile' ,vendor_price='$vendor_price'  v_id='$v_id' ";    if (mysqli_query($conn, $sql))      {          if(move_uploaded_file($_files['image']['tmp_name'], $target))                 {                 $image = $_files["image"]["name"];                 $success = "✓ updated";                 $sql = "update my_veh_ven set image='$image' v_id='$v_id' ";                 mysqli_query($conn, $sql)                 }     }   else    {                 $fail = "x  not updated";    }    }      mysqli_close($conn);   ?>
