I could really use some help. I am a bit new to all. And I am trying to make an tool to delete rows from a table of my database. This is what I came up with so far, it can show the rows from the table with a checkbox linked to that row and a delete button to delete the selected rows. But when I hit delete I get the following error message.
Warning: mysql_real_escape_string() expects parameter 1 to be string, array given in /home/a9083956/public_html/zundappgroesbeek/beheer/testretrievesql.html on line 31
Beneath this the code:
<html>
<head>
<title>Retrieve and delete data from database </title>
</head>
<body>
<form action="" method="post">
<?php
// Connect to database server
mysql_connect("mysql7.000webhost.com", "a9083956_test", "sesam") or die (mysql_error ());
// Select database
mysql_select_db("a9083956_test") or die(mysql_error());
// SQL query
$strSQL = "SELECT * FROM forum_question";
// Execute the query (the recordset $rs contains the result)
$rs = mysql_query($strSQL);
// Loop the recordset $rs
// Each row will be made into an array ($row) using mysql_fetch_array
while($row = mysql_fetch_array($rs)) {
// Write the value of the column FirstName (which is now in the array $row)
echo '<input name="delete[]" type="checkbox">';
echo $row['topic']. " " .$row['name']. " " .$row['datetime'] . "<br />";
}
$delete = mysql_real_escape_string($_POST['delete']);
for($i=0; $i < count($delete); $i++){
mysql_query("DELETE FROM table_name WHERE id = $delete[$i] ");
}
// Close the database connection
mysql_close();
?>
<input type="submit" value="Delete selected items">
</form>
</body>
</html>
