我的分页脚本中的链接在第 1 页后消失

我又回来了，遇到了PHP mySQLi分页问题...当我运行脚本时，它对第一页工作正常，但是当 y 单击指向第二页的链接时，链接有效，但分页消失了。所以如果我现在有 3 个链接，我看不到。这是我的代码。

<?php
    include_once ('myConnection.php');
    if ( isset( $_GET["get_name"] ) ) { 
        $las_escuelas = $_GET["get_name"];
    } else { 
        $las_escuelas = 1; 
    };
    $start_from = ( $las_escuelas - 1 ) * 10;
    $escuelas = "SELECT * 
                   FROM escuelas 
                   WHERE delegacion = '$delegacion' 
                     AND nivel = '$nivel' 
                   ORDER BY nombre ASC 
                   LIMIT $start_from, 10";
    $consulta = mysqli_query( $miguia, $escuelas ) or die ( mysqli_error() );
    while ( $fila = mysqli_fetch_array( $consulta ) ) {
        echo $fila['name'] . '<br>' . $fila['street'] . ' ' . $fila['numero'] . ' ' . $fila['place'] . ' ' . $fila['phone'] . '<br>';
    };
    $escuelas = "SELECT COUNT(delegacion) 
                   FROM escuelas 
                   WHERE delegacion = '$delegacion' 
                     AND nivel = '$nivel'";
    $consulta = mysqli_query( $miguia, $escuelas );
    $fila = mysqli_fetch_row( $consulta );
    $registros_total = $fila[0];
    $paginas_total = ceil( $registros_total / 10 );
    for ( $i = 1; $i <= $paginas_total; $i++ ) {
        echo "<a href='resultados1.php?las_escuelas=".$i."'>".$i."</a> ";
    };
?>

谢谢:)
