PHP에서 검색 필터를 추가

Question

이것은 검색 엔진입니다. & "검색"에있는 단어에 따라 하나의 필터가있는 페이지 매김입니다. 두 개의 검색 필터를 추가하고자합니다 : 역할 & 두 날짜 사이에서 검색하십시오.

<?php 

$button = $_GET ['submit']; 
$search = $_GET ['search']; 

echo "You searched for <b>$search</b> <hr size='1'></br>"; 
mysql_connect("localhost","root",""); 
mysql_select_db("page"); 

$search_exploded = explode (" ", $search); 

foreach($search_exploded as $search_each) 
{$x=0; 
$construct=""; 
$x++; 
if($x==1) 
$construct .="name LIKE '%$search_each%'"; 

} 

$constructs ="SELECT * FROM info WHERE $construct"; 
$run = mysql_query($constructs); 

$foundnum = mysql_num_rows($run); 

if ($foundnum==0) 
echo "Sorry"; 
else 
{ 

echo "$foundnum results found !<p>"; 
$per_page = 1; 
$start = $_GET['start']; 
$max_pages = ceil($foundnum/$per_page); 
if(!$start) 
$start=0; 
$getquery = mysql_query("SELECT * FROM info WHERE $construct LIMIT $start, $per_page"); 

while($runrows = mysql_fetch_assoc($getquery)) 
{ 
$name = $runrows ['name']; 
} 

//Pagination Starts 
echo "<center>"; 

$prev = $start - $per_page; 
$next = $start + $per_page; 

$adjacents = 3; 
$last = $max_pages - 1; 

if($max_pages > 1) 
{ 
//previous button 
if (!($start<=0)) 
echo " <a href='index.php?search=$search&submit=Search+source+code&start=$prev'>Prev</a> ";  

//pages

Answer 1

당신은 그렇지 않으면 당신이 지속적으로 (어쨌든 필요가 없습니다) $x의 가치와 $construct을 재설정이

//by name 
$construct="true"; 
foreach($search_exploded as $search_each) { 
    $construct .= " AND name LIKE '%$search_each%'"; 
} 
//by role 
if($role) { 
    $construct .= " AND role = '$role'"; 
} 
//by date 
if($start) { 
    $construct .= " AND the_date >= '$start'"; 
} 
if($end) { 
    $construct .= " AND the_date <= '$end'"; 
} 

처럼 루프를 다시 작성해야합니다.

물론 GET의 날짜/역할을 적절하게 형식화해야합니다.
