MYSQL PHP pagination not working links - php

Question

I'm trying to make a pagination, i've got next code but i cant get it working.
<?php
$link = mysqli_connect("localhost", "", " ", "");
if($link === false) { die('<span class="rosu">EROARE:</span> Nu s-a putut realiza conexiunea la baza de date.<br/><br/>Va rog verificati conexiunea pentru baza de date.<br/>' . mysqli_connect_error()); }
$num_rec_per_page=10;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $num_rec_per_page;
$sql = "SELECT * FROM My_Contracte WHERE contract_sters='nu' ORDER BY id_contract DESC LIMIT $start_from, $num_rec_per_page";
$rs_result = mysql_query ($sql); //run the query
if($result = mysqli_query($link, $sql)){
if(mysqli_num_rows($result) > 0){
echo '<table id="contracte">';
echo "<tr>";
echo "<th>EDT</th>";
echo "<th>Numar Contract</th>";
echo "<th>C</th>";
echo "<th>Data Realizare</th>";
echo "<th>Nume Firma</th>";
echo "<th>Nume Locatie</th>";
echo "<th>Zona Judet</th>";
echo "<th>Servicii</th>";
echo "<th>Suma Plata</th>";
echo "<th>PER. CTR.</th>";
echo "<th>Nume Contact</th>";
echo "<th>Telefon</th>";
echo "<th>E</th>";
echo "<th>T</th>";
echo "<th>W</th>";
echo "<th>DEL</th>";
echo "</tr>";
while($row = mysqli_fetch_array($result)){
echo "<tr>";
echo "<td class='editbutton'><a href='modifica.php?ID=" . $row['id_contract'] . "'><img src='images/edit.png'></img></a></td>";
echo '<td>' . $row['numar_contract'] . ' <img src="images/link.png" width="14px"></img></td>';
echo "<td><a href='pdf/" . $row['link_contract_pdf'] . "' target='_blank'><img src='images/pdf.png' width='20px'></img></a></td>";
echo "<td>" . $row['expirare_contract'] . "</td>";
echo "<td>" . $row['nume_firma'] . "</td>";
echo "<td>" . $row['nume_locatie'] . "</td>";
echo "<td>" . $row['zona_judet_oras'] . "</td>";
echo "<td>" . $row['servicii_oferite'] . "</td>";
echo "<td>" . $row['suma_de_plata'] . "</td>";
echo "<td>" . $row['perioada_contract'] . "</td>";
echo "<td>" . $row['nume_contact'] . "</td>";
echo "<td>" . $row['telefon_contact'] . "</td>";
echo '<td><img src="images/email.png"></img></td>';
echo '<td><img src="images/turvirtual.png"></img></td>';
echo '<td><img src="images/website.png"></img></td>';
echo "<td class='deletebutton'><img src='images/delete.png'></img></td>";
echo "</tr>";
}
echo "</table>";
mysqli_free_result($result);
} else { print ('<span class="rosu">EROARE!</span> Nu am gasit contracte in baza de date.'); }
} else { print ('<span class="rosu">EROARE!</span> Nu s-a putut executa comada de listare a contractelor.<br/><br/><b>Motivul pentru care nu s-a putut accesa tabelul: </b>') . mysqli_error($link); print '.'; }
?>
<?php
$sql = "SELECT * FROM My_Contracte WHERE contract_sters='nu'";
$total_records = mysql_num_rows($sql); //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);
echo "<a href='lista.php?page=1'><div class='pagina'>1</div></a> "; // Goto 1st page
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='lista.php?page=".$i."'><div class='pagina'>".$i."</div></a> ";
};
echo "<a href='lista.php?page=$total_pages'><div class='pagina'>$total_pages</div></a> "; // Goto last page
?>
The problem is that i get it paginated but it dosnt show right links. so i think the problem is in the next code:
<?php
$sql = "SELECT * FROM My_Contracte WHERE contract_sters='nu'";
$total_records = mysql_num_rows($sql); //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);
echo "<a href='lista.php?page=1'><div class='pagina'>1</div></a> "; // Goto 1st page
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='lista.php?page=".$i."'><div class='pagina'>".$i."</div></a> ";
};
echo "<a href='lista.php?page=$total_pages'><div class='pagina'>$total_pages</div></a> "; // Goto last page
?>
Thank you!

EDIT:
[02-Oct-2015 12:18:57 Europe/Bucharest] PHP Warning: mysql_num_rows() expects parameter 1 to be resource, string given in /lista.php on line 81
I get this error in error_log.
81 line is:
$total_records = mysql_num_rows($sql);

Answer 1

Try this i guess you already put link for first and last page and again you are doing that in loop.
for ($i=2; $i<$total_pages; $i++) {
echo "<a href='lista.php?page=".$i."'><div class='pagina'>".$i."</div> </a> ";
};

Answer 2

I got it working like this:
<?php
include("db.php");
$sql = mysql_query("SELECT COUNT(id_contract) FROM My_Contracte WHERE contract_sters = 'nu'");
$total_records = mysql_result($sql, 0);
$total_pages = ceil($total_records / $num_rec_per_page);
echo "<a href='lista.php?page=1'><div class='pagina'>1</div></a> ";
for ($i=2; $i<=$total_pages; $i++) {
echo "<a href='lista.php?page=".$i."'><div class='pagina'>".$i."</div></a> ";
};
?>
