Searchbar

[andy_b_1502]

Hi everyone.

 

I have a search bar on my site here is the form:

 

<form method="post" action="search2.php">
  <input type="text" onFocus="if(this.value=='Search')this.value='';" onBlur="if(this.value=='')this.value='Search';" value="Search"  id="search-field"/>
  <input type="submit" value="" id="search-btn"/>
  </form> 

 

What is the variable to use here? so i can make search2.php.. or can i NOT use this with php?

 

Please help, many thanks

Give your input box a name, for example:

 

<input type="text" name="strSearch" onFocus="if(this.value=='Search')this.value='';" onBlur="if(this.value=='')this.value='Search';" value="Search"  id="search-field"/>

 

Then, at the top of search2.php, check the value of: $_POST['strSearch']

Thanks, so search2.php (now changed to search.php) looks like this but i'm getting a 404 error, iv'e ftp'd it to server though??

 

Could you just tell me if there's anything suspect/wrong with my coding so i can then check my cpanel for the file

 

<?PHP
session_start();
include ('php only scripts/db.php');

// Get the search variable from URL
  $var = @$_GET['strSearch'] ;
  $trimmed = trim($var); //trim whitespace from the stored variable

// rows to return
$limit=10; 

// check for an empty string and display a message.
if ($trimmed == "")
  {
  echo "<p>Please enter a search...</p>";
  exit;
  }

// check for a search parameter
if (!isset($var))
  {
  echo "<p>We dont seem to have a search parameter!</p>";
  exit;
  }

// Build SQL Query  
$query = "(SELECT postcode, company_name FROM companies
             WHERE postcode like '%$trimmed%')                  
	  ORDER BY postcode"; // EDIT HERE and specify your table and field names for the SQL query

$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);
$result = mysql_query($query) or die("<b>Query:</b> $query<br><b>Error</b>: " . mysql_error());



// If we have no results, offer a google search as an alternative

if ($numrows == 0)
  {
  echo "<h4>Results</h4>";
  echo "<p>Sorry, your search: "" . $trimmed . "" returned zero results</p>";

// google
echo "<p><a href=\"http://www.google.com/search?q=" 
  . $trimmed . "\" target=\"_blank\" title=\"Look up 
  " . $trimmed . " on Google\">Click here</a> to try the 
  search on google</p>";
  }

// next determine if s has been passed to script, if not use 0
  if (empty($s)) {
  $s=0;
  }

// get results
  $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");


// display what the person searched for
echo "<p>You searched for: "" . $var . ""</p>";

// begin to show results set
echo "<a href=\"localarea.php?var=$var\">Results for $q;</a>";
$count = 1 + $s ;

// now you can display the results returned
  while ($row= mysql_fetch_array($result)) {
  $title = $row['postcode'];
  $name = $row['company_name'];

  echo " $title" ;
  echo " $company_name" ;
  $count++ ;
  }

$currPage = (($s/$limit) + 1);

//break before paging
  echo "<br />";

  // next we need to do the links to other results
  if ($s>=1) { // bypass PREV link if s is 0
  $prevs=($s-$limit);
  print " <a href=\"$PHP_SELF?s=$prevs&q=$var\"><< 
  Prev 10</a>&nbsp ";
  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo " <a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 >></a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>Showing results $b to $a of $numrows</p>";
  
  
?>

<?php echo  "<a href=\"localarea.php?var=$var\">"$var"</a>";?>

Not sure why you would get a 404 - is the page definitely up there?

 

Try typing it in: www.yourdomain.com/search.php

 

Also, if you're posting the form, this line is incorrect:

$var = @$_GET['strSearch'] ;

 

It should be:

$var = @$_POST['strSearch'];

Sorry, that's sorted it, changed the get to post and there was a mistake in my include.

 

Thank you for your help
