أحاول تنفيذ بحث عن مشروع أعمل عليه حاليًا.المشكلة التي أواجهها هي عندما أذهب إلى الصفحة الثانية ستكون نتيجة البحث خاطئة.
هذا هو نموذج البحث الموجود في ملف header.php الخاص بي
<form name="search" id="search" method="post" action="search.php">
<input type="text" tabindex="1" class="input" id="term" name="term" value=""/>
<input type="submit" tabindex="2" id="submit" value="SEARCH" />
إليك كود php لصفحة البحث الخاصة بي
<?php include ('header.php');
$term = $_POST['term'];
$queryn = mysql_query("select * from scripts where title like '%$term%' or discription like '%$term%' and approved='1'") or die (mysql_error());
$search_num_rows = mysql_num_rows($queryn);
?>
<div class="cat_script_container">
<div class="nresults">Found <?php echo $search_num_rows;?> results for "<?php echo $term;?>"</div>
<?php

أتساءل عن أي طريقة لإعطاء إجراء نموذج البحث مثل الإجراء = "search.php?term=keyword".أعتقد أنه إذا كان بإمكاني نشر عنوان url مثل هذا، فيمكنني استخدام $_GET لأخذ keyworkd.إذا كان أي شخص يمكن أن يساعدني في هذا بأي حال من الأحوال فأنا خصصته حقًا.شكرا مقدما.
المحلول
تغيير الخاص بك action يعزو إلى get
<form name="search" id="search" method="get" action="search.php">
بهذه الطريقة سيتم إلحاق قيم النموذج الخاص بك search.php على التقديم.
على سبيل المثال:
search.php?term=the_term
