Question

ID    CODE      STATE    CITY            AREA
1   SBIN0000952 ORISSA  JAIPUR          TOWN
2   SBIN0000953 ORISSA  KURAPUT         VILLAGE
3   SBIN0000954 DELHI   DELHI           TOWN
4   SBIN0000955 DELHI   NEW DELHI       VILLAGE
5   SBIN0000956 GOA     SOUTH GOA       VILLAGE
6   SBIN0000957 GOA     PANAJI          TOWN
7   SBIN0000958 KERLA   CHOCHIN         TOWN
8   SBIN0000959 KERLA   TRIVANDRAM      VILLAGE
9   SBIN0000960 ANDHRA  VIZAG           TOWN
10  SBIN0000961 ANDHRA  HYDERABAD       VILLAGE

above is my table and i want search a multiple keyword for example

kerla town then it should display the record

7   SBIN0000958 KERLA   CHOCHIN    TOWN

below my present code in php

include('dbConnect.inc.php');

//collect
if(!isset($_POST['search'])){
    header("Location:index.php");

} 
    $searchq = mysql_real_escape_string( $_POST['search']);
    $search_sql = "SELECT * FROM `bankifscin` WHERE STATE LIKE '%$searchq%' OR CITY LIKE '%$searchq%' OR CODE LIKE '%$searchq%' ";
    $search_query = mysql_query($search_sql) or die(mysql_error());
    if(mysql_num_rows($search_query)!=0){
    $search_rs = mysql_fetch_assoc($search_query);
    }

to print

<?php if(mysql_num_rows($search_query)!=0){
    do{ ?>

    <?php 

    $bank = $search_rs['BANK'];
    $ifsc = $search_rs['IFSC'];
    $branch= $search_rs['BRANCH'];
    $micr = $search_rs['MICR_CODE'];
    $address = $search_rs['ADDRESS'];
    $contact = $search_rs['CONTACT'];
    $city = $search_rs['CITY'];
    $district = $search_rs['DISTRICT'];
    $state = $search_rs['STATE'];
         ?>
         <table width="100%" border="2" bordercolor="#000" class="bdrcolor">


    <tbody>     
  <tr>
    <td width="15%"><?=$bank?></td> 
       <td width="15%"><?=$branch?></td>
       <td width="15%"><b>IFSC:</b><?=$ifsc?> <br /><b>MICR:</b><?=$micr?></td>
       <td width="20%"><?=$address?><br /> <b>City :</b><?=$city?> <br /> <b>District :</b><?=$district?> <br /> <b>State:</b> <?=$state?></td> 
       <td width="10%"><?=$contact?></td>
  </tr>
  <br />
  </tbody>
</table>



    <?php   }while ($search_rs = mysql_fetch_assoc($search_query)); 

}else{
        echo "No Results";

        }


    ?>

its only giving the result of one keyword or no result

Answer 1

You should iterate your result set, to see all records.

    $result = mysql_query($query);
    if ($result != NULL)
    {
      while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
      {
        foreach ($row as $key => $value)
        {
          // todo: use $key and $value
        }
      }
      mysql_free_result($result);
   }

EDIT:

In case you wondered, the call mysql_fetch_array($result, MYSQL_ASSOC) really is the same thing as mysql_fetch_assoc($result) .

EDIT:

If you want only to see the records that contain ALL keywords. Then you should change your SQL query, you need to use AND instead of OR in your sql query.

"SELECT * FROM `bankifscin` WHERE STATE LIKE '%$state%' AND CITY LIKE '%$city%' AND CODE LIKE '%$code%' ";

I guess not all keywords are used at all time. So you may want to build that query at runtime.

$query = "SELECT * FROM `bankifscin` WHERE 1=1";
if ($useCity) $query .= " AND city like '%{$city_keyword}%'";
if ($useState) $query .= " AND state like '%{$state_keyword}%'";
if ($useCode) $query .= " AND code like '%{$code_keyword}%'";

I didn't understand that very well from your question. Maybe you only want to include the keywords if they are specified ? (eg $useCity = ($city_keyword != null); )

EDIT:

From what I understood from your last post. You want the input to be split in words. And each word must match at least 1 column. Meaning all words must be used to query. Then you could try this:

// split the input in words
$searchq = $_POST['search'];
$words = explode(" ", $searchq);
$wordCount = count($words);

// declare which columns should be searched
$columns = array("city", "town", "code", "area");
$columnCount = count($columns);

// start from a basic query, which we will expand later
$query = "SELECT * FROM `bankifscin` WHERE ";

// all words should be used
// that's why we are adding them with the 'AND' operator.
for($i=0;$i<$wordCount;$i++)
{
  $word = mysql_escape_string($words[$i]);
  if ($i > 0) $query .= " AND ";

  // build the condition
  $condition = " (";
  for($j=0;$j<$columnCount;$j++)
  {
    // but each word can match any column, doesn't matter which one.
    // that's why we are using the 'OR' operator here. 
    if ($j > 0) $condition .= " OR ";
    $column = $columns[$j];
    $condition .= " {$column} like '%{$word}%' ";
  }
  $condition .= ") ";
  $query .= $condition;
}
echo $query;

The trick here is that by building your sql at runtime, it will produce a totally different query depending on the number of words the user has used.

Answer 2

I am assuming that you are only getting one row. You need to replace the spaces in your string with commas and use something like this.

$search_sql = "SELECT * FROM bankifscin WHERE STATE in ($searchq) OR CITY in ($searchq) OR CODE in ($searchq)";

Answer 3

You are going in the wrong direction. You are printing the table in the if condition. You should be doing the printing part in the foreach loop. You just have to define the <table> outside the foreach loop.

You have to use foreach loop

<table>
   <?php
       $result = mysql_query($query);
        if (!$result)
        {
          while ($row = mysql_fetch_array($result))
          {
            foreach ($row as $key => $value)
            {
               <tr>  /* (print the values ) */ </tr>
            }
          }
       }
 ?>
</table>

NOTE:

Please stop using mysql* , start using mysqli* functions

Answer 4

 include('dbConnect.inc.php');

 //collect
     if(!isset($_POST['search'])){
   header("Location:index.php");

 } 
$searchq = mysql_real_escape_string( $_POST['search']);
$search_sql = "SELECT * FROM `bankifscin` WHERE STATE='%$searchq%' and`enter code here` CITY= '%$searchq%'";
$search_query = mysql_query($search_sql) or die(mysql_error());
if(mysql_num_rows($search_query)!=0){
$search_rs = mysql_fetch_assoc($search_query);
}
