I downloaded a zip file from a database but am unable to find what I should put in the $file_names = array()? When I run the file the error displayed is No ID Selected
I think that this is because there is nothing inside the array(). Can someone help me define the array()?
<?php
$file_names = array();
// Make sure an id was passed
if (isset($_GET['id'])) {
// Get the id into string (in case of an array)
$id_pass = implode(",",$_GET['id']);
// Make sure the name is in fact a valid
if ($id_pass <= 0) {
die ('No ID Selected!');
} else {
// codes to connect to the database is here
// Fetch the file information
$query = "select * from docu where id = {$id_pass};";
var_dump($result);
$result = $dbLink->query($query);
if ($result) {
// Make sure the result is valid
if ($result->num_rows == 1) {
// Get the row
$row = mysqli_fetch_assoc($result);
//zip function
$zip = new ZipArchive();
$filename = "export_" . date('Y.m.d H.i.s') . ".zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE) !== true) {
echo "Cannot Open for writing";
}
$ext = $row['name'] . ".pdf"; // taking file name from DB and adding extension separately
$zip->addFromString($ext, $row['content']); //adding blob data from DB
$zip->close();
header("Content-disposition: inline; filename='.$filename'");
header('Content-type: application/zip');
readfile($filename);
unlink($filename);
}
}
// Free the mysqli resources
mysqli_free_result($result);
mysqli_close($dbLink);
}
}
result of var_dump($result):
object(mysqli_result)#2 (5) { ["current_field"]=> int(0) ["field_count"]=> int(2) ["lengths"]=> NULL ["num_rows"]=> int(22) ["type"]=> int(0) }
Here is the HTML Form.
<html>
<form action="test.php" method="get"/>
<?php
//codes to connect to the database is here
mysqli_select_db($con, "images");
$query = "SELECT id, name FROM docu order by id";
$result = mysqli_query($con, $query) or die('Error, query failed');
if (mysqli_num_rows($result) == 0) {
echo "Database is empty <br>";
} else {
while ((list($id, $name) = mysqli_fetch_array($result, MYSQLI_BOTH))) {
echo "<input type='checkbox' name='id[]'>";
echo $name . " " . $id . " " . "<br>"; //id and name removed
}
}
?>
<input type="submit" name="submit" value="Submit" />
</html>
