I'm trying to create function that insert into DB
need to add this function into insert.php but i really donno how to write this function properly using pagination.php
help needed badly !
Code:
function insertrow () {
$sql = "INSERT INTO mytable(title) VALUES ('textarea text')";
$pager = new PS_Pagination($conn, $sql);
$pager->setDebug(true);
$rs = $pager->paginate();
if(!$rs){
echo "Invalid query: ".mysql_error()." <br>\n ";
}
}
insert.php:
PHP Code:
<?php
include('pagination.php');
$conn = mysql_connect('localhost','root','123456');
if(!$conn){
echo "Invalid query: ".mysql_error()." <br>\n ";
}
$status = mysql_select_db('fblike', $conn);
if(!$status){
echo "Invalid query: ".mysql_error()." <br>\n ";
}
echo "<html>\n" ;
echo "<head>\n" ;
echo "<title>Insert !</title>\n" ;
echo "</head>\n" ;
echo "<body>\n" ;
echo "<form method=\"post\" action=\"\">\n" ;
echo "Insert Row: <br> <textarea rows=\"1\" cols=\"60\" name=\"quote\" wrap=\"physical\" > Enter your favorite quote! </textarea> \n" ;
echo "<input type=\"submit\" name=\"submit\" value=\"Insert\">\n" ;
echo "</form>\n" ;
echo "<br>\n" ;
$sql = 'SELECT * FROM mytable';
$pager = new PS_Pagination($conn, $sql, 10, 8, "param1=valu1¶m2=value2");
$pager->setDebug(true);
$rs = $pager->paginate();
if(!$rs){
echo "Invalid query: ".mysql_error()." <br>\n ";
}
while($row = mysql_fetch_assoc($rs)) {
echo " {$row['title']} ---------------------------> <a href= \"\">Edit</a><br><br>\n";
}
echo "<br>\n" ;
echo $pager->renderFullNav();
echo "</body>\n" ;
echo "</html>\n" ;
?>
