PHP - 検索結果が改ページされていません

Question

データベースに10個以上の項目がある場合、ページングするように検索結果を取得しようとしています。何らかの理由で、コードが10個以上の項目を認識して後続ページのリンクを作成しても、すべての検索結果が最初のページにのみ表示されます。誰でもお手伝いできますか？コードは以下の通りです：

for($i = 0; $i < $terms_count; $i++) 
{ 
    $search_terms_array[$i] = trim($search_terms_array[$i]); 
    ${"query".$i} = $this->mysqli_link->query("SELECT prod_id, prod_tags FROM table WHERE prod_tags LIKE '%" . $search_terms_array[$i] . "%'"); 
    if(${"query".$i}->num_rows < 1) 
    { 
     $zerocount++; 
    } 
    else 
    { 
     $rows = array(); 
     while($row = ${"query".$i}->fetch_array()) 
     { 
      $rows[] = $row; 
     } 
     foreach($rows as $row) 
     { 
      $search_id_results[] = $row['prod_id']; 
     } 
    } 
} 
if($zerocount == $terms_count) 
{ 
    echo $this->err_handle->fetch_error_text("search_terms_0_results"); 
    return; 
} 
else 
{ 
    $search_results = array_values(array_unique($search_id_results)); 
    $search_results_count = count($search_results); 
    $search_page_count = ceil($search_results_count/10); 
    $search_page_first_result = ($search_page - 1) * 10; 
    echo '<p>Go to page: '; 
    for($i = 1; $i <= $search_page_count; $i++) 
    { 
     if($i == $search_page) 
     { 
      echo "&nbsp;<strong>" . $i . "</strong>"; 
     } 
     else 
     { 
      echo '&nbsp;<a href="index.php?section=products&amp;action=search&amp;page=' . $i . '">' . $i . '</a>'; 
     } 
    } 
    echo '</p><p>&nbsp;</p><p>&nbsp;</p>'; 
    for($i = 0; $i < $search_results_count; $i++) 
    { 
     $query = $this->mysqli_link->query("SELECT * FROM table WHERE prod_id='" . $search_results[$i] . "' LIMIT " . $search_page_first_result . ", 10"); 
     while($row = $query->fetch_array()) 
     { 
     echo "<h4><a href=\"index.php?section=products&amp;subsection=" . $row['prod_category'] . "&amp;prodid=" . $row['prod_id'] . "\">" . $row['prod_name'] . "</h4></a><p><img src=\"includes/images/product_images/" . $row['prod_category'] . "/" . $row['prod_pic_filename'] . "\" alt=\"\" width=\"150\" height=\"200\" /></p><p>Price: £" . $row['prod_price'] . "</p><p>" . $row['prod_code'] . "</p><input type=\"number\" name=\"prod_qty\" maxlength=\"2\" /><input type=\"submit\" name=\"add_to_basket\" value=\"Add To Basket\" /></form></p><p>&nbsp;</p><p>&nbsp;</p>"; 
     } 
    } 
    echo '<p>Go to page: '; 
    for($i = 1; $i <= $search_page_count; $i++) 
    { 
     if($i == $search_page) 
     { 
      echo "&nbsp;<strong>" . $i . "</strong>"; 
     } 
     else 
     { 
      echo '&nbsp;<a href="index.php?section=products&amp;action=search&amp;page=' . $i . '">' . $i . '</a>'; 
     } 
    } 
    echo '</p><p>&nbsp;</p><p>&nbsp;</p>'; 
}

[OK]をので、私は、この問題に対する解決策を見つけ、次のように完全な機能は以下のようになります。

public function product_search($search_terms, $search_page, $search_flag_check) 
{ 
    if($search_flag_check == "invalid") 
    { 
     echo $this->err_handle->fetch_error_text("invalid_ns_term"); 
     return; 
    } 
    if($search_terms == "") 
    { 
     echo $this->err_handle->fetch_error_text("no_search_string"); 
     return; 
    } 
    $search_terms = htmlspecialchars($search_terms); 
    $search_terms = $this->mysqli_link->real_escape_string(filter_var($search_terms, FILTER_SANITIZE_FULL_SPECIAL_CHARS, FILTER_FLAG_NO_ENCODE_QUOTES)); 
    $search_terms_array = explode(" ", $search_terms); 
    $terms_count = count($search_terms_array); 
    $zerocount = 0; 
    $search_id_results = array(); 
    for($i = 0; $i < $terms_count; $i++) 
    { 
     $search_terms_array[$i] = trim($search_terms_array[$i]); 
     ${"query".$i} = $this->mysqli_link->query("SELECT prod_id, prod_tags FROM table WHERE prod_tags LIKE '%" . $search_terms_array[$i] . "%'"); 
     if(${"query".$i}->num_rows < 1) 
     { 
      $zerocount++; 
     } 
     else 
     { 
      $rows = array(); 
      while($row = ${"query".$i}->fetch_array()) 
      { 
       $rows[] = $row; 
      } 
      foreach($rows as $row) 
      { 
       $search_id_results[] = $row['prod_id']; 
      } 
     } 
    } 
    if($zerocount == $terms_count) 
    { 
     echo $this->err_handle->fetch_error_text("search_terms_0_results"); 
     return; 
    } 
    else 
    { 
     $search_results = array_values(array_unique($search_id_results)); 
     $search_results_count = count($search_results); 
     $search_page_count = ceil($search_results_count/10); 
     $search_page_first_result = ($search_page - 1) * 10; 
     $search_page_results_limit = 10; 
     if($search_page_first_result < 1) 
     { 
      $search_page_first_result = 1; 
     } 
     echo '<p>Go to page: '; 
     for($i = 1; $i <= $search_page_count; $i++) 
     { 
      if($i == $search_page) 
      { 
       echo "&nbsp;<strong>" . $i . "</strong>"; 
      } 
      else 
      { 
       echo '&nbsp;<a href="index.php?section=products&amp;action=search&amp;page=' . $i . '">' . $i . '</a>'; 
      } 
     } 
     echo '</p><p>&nbsp;</p><p>&nbsp;</p>'; 
     $search_page_upper_limit = $search_page_first_result + 9; 
     if(array_key_exists($search_page_upper_limit, $search_results)) 
     { 
      $search_results_limit = $search_page_first_result + $search_page_results_limit; 
     } 
     else 
     { 
      end($search_results); 
      $search_results_limit = key($search_results); 
      reset($search_results); 
     } 
     for($i = $search_page_first_result; $i <= $search_results_limit; $i++) 
     { 
      $query2 = $this->mysqli_link->query("SELECT * FROM table WHERE prod_id='" . $search_results[$i] . "'"); 
      $row = $query2->fetch_array(); 

      echo "<h4><a href=\"index.php?section=products&amp;subsection=" . $row['prod_category'] . "&amp;prodid=" . $row['prod_id'] . "\">" . $row['prod_name'] . "</h4></a><p><img src=\"includes/images/product_images/" . $row['prod_category'] . "/" . $row['prod_pic_filename'] . "\" alt=\"\" width=\"150\" height=\"200\" /></p><p>Price: £" . $row['prod_price'] . "</p><p>" . $row['prod_code'] . "</p><input type=\"number\" name=\"prod_qty\" maxlength=\"2\" /><input type=\"submit\" name=\"add_to_basket\" value=\"Add To Basket\" /></form></p><p>&nbsp;</p><p>&nbsp;</p>"; 

     } 
     echo '<p>Go to page: '; 
     for($i = 1; $i <= $search_page_count; $i++) 
     { 
      if($i == $search_page) 
      { 
       echo "&nbsp;<strong>" . $i . "</strong>"; 
      } 
      else 
      { 
       echo '&nbsp;<a href="index.php?section=products&amp;action=search&amp;page=' . $i . '">' . $i . '</a>'; 
      } 
     } 
     echo '</p><p>&nbsp;</p><p>&nbsp;</p>'; 
    } 
} 

それは思考のビットを取って、私はあきらめるとしていました、しかし、配列キーを使って各検索ページの制限を計算し、関連するPHP配列関数をグーグルで検索したところ、すべてがかなりうまく収まったと思った。 私はこのコードが今はあまり整頓されていない可能性があることを理解しています。
