i want to populate a drop down list from my sql database using php, but it shows the below error:
"Warning: mysql_fetch_array() expects parameter 1 to be resource, object given in C:\\wamp\\www\\Q&A\\signup.php on line 43"
my code is:
<?php
$sql = "SELECT category_name FROM category ORDER BY RAND() LIMIT 1";
$result=mysqli_query($conn, $sql) or die ("Query to get data from category failed: ".mysql_error());
while ($row = mysql_fetch_array($result)) {
$category_name=$row["category_name"];
echo "<option>" . $category_name . "</option>";
}
?>
It's because you're using old function mysql_fetch_array
it should be mysqli_fetch_array
.
Also mysql_error
should be mysqli_error
which accepts connection as single parameter.
Update your code like this,
<?php
$sql = "SELECT category_name FROM category ORDER BY RAND() LIMIT 1";
$result=mysqli_query($conn, $sql) or die ("Query to get data from category failed: ".mysqli_error(conn));
while ($row = mysqli_fetch_array($result)) {
$category_name=$row["category_name"];
echo "<option>" . $category_name . "</option>";
}
?>
I'm assuming you've a valid connection to the database in $conn
variable.
