combining search fields into one

combining search fields into one

Hi

I've used DA to create search/results pages. Currently there are 3 search boxes, for the fields PgTitle, PgDesc and PgDetails.

This search works fine (additional parameters are used to restrict records to SiteID etc).

What I would like to do is have one search field, which looks for matches in any of those 3 fields.

I've tried changing the following in different ways:

//comparison list additions
$WADbSearch1->addComparisonFromEdit("PgTitle","S_PgTitle","AND","Includes",0);
$WADbSearch1->addComparisonFromEdit("PgDesc","S_PgDesc","AND","Includes",0);
$WADbSearch1->addComparisonFromEdit("PgDetails","S_PgDetails","AND","Includes",0);

However, when I try to combine them into one, I either get ALL records for the particular SiteID or no records (even though I am testing with criteria I know should work).

ANy suggestions? I might well be looking at the wrong piece of code - but I can't see anything else that looks likely.

Many thanks
Chris

Are you trying to do the search from a single text field ?

lets call your single search text field 'searchtext'

try this

//comparison list additions
$WADbSearch1->addComparisonFromEdit("PgTitle","searchtext","AND" ,"Includes",0);
$WADbSearch1->addComparisonFromEdit("PgDesc","searchtext","AND"," Includes",0);
$WADbSearch1->addComparisonFromEdit("PgDetails","searchtext"," AND","Includes",0);

HI Craig

Thanks - that's what I thought it would be, but I've tried it already and it didn't work.

Also tried changing "AND" to "OR", equally without success.

Cheers

Just noticed the differeny spacing around "AND" - either "AND ", "AND" or " AND". Don't know if this will make a difference, but will experiment tomorrow (late now!) and feedback.

This is a sample of code that I use to perform single field text searches. I use GET rather than POST in this instance but it should give you the basis to get started

php:
//WA Database Search (Copyright 2005, WebAssist.com)

//Recordset: rsDataSet;
//Searchpage: search-form.php;
//Form: frmSearch;
$WADbSearch1_DefaultWhere = "";
if (!session_id()) session_start();
if ((isset($_GET["WADbSearch1"])) && ($_GET["WADbSearch1"] != "")) {
  $WADbSearch1 = new FilterDef;
  $WADbSearch1->initializeQueryBuilder("MYSQL","1");
  //keyword array declarations
  $KeyArr0 = array("PgTitle");
  $KeyArr1 = array("PgDesc");
  $KeyArr2 = array("PgDetails");

  //comparison list additions
  $WADbSearch1->keywordComparison($KeyArr0,"".((isset($_GET["searchtext"]))?$_GET["searchtext"]:"")  ."","AND","Includes",",%20","%20","%22","%22",0);
  $WADbSearch1->keywordComparison($KeyArr1,"".((isset($_GET["searchtext"]))?$_GET["searchtext"]:"")  ."","OR","Includes",",%20","%20","%22","%22",0);
  $WADbSearch1->keywordComparison($KeyArr2,"".((isset($_GET["searchtext"]))?$_GET["searchtext"]:"")  ."","OR","Includes",",%20","%20","%22","%22",0);

Hi Dave

Many thanks for replying.

I'm using 'GET' so that the SiteID and lang parameters are captured.

Unfortunately, I'm not making any progress. All pages belonging to the SiteID are returned - at least it's not returning others'!

The form code:
<form action="search_results2.php" method="get" name="WADASearchForm" id="WADASearchForm">
<div class="WADAHorizLine"></div>
<table class="WADADataTable" cellpadding="0" cellspacing="0" border="0">
<tr>
<th class="WADADataTableHeader"><span class="WADADataNavButtonCell">
<input name="SiteID" type="hidden" id="SiteID" value="<?php echo $_GET['SiteID']; ?>" />
<input name="lang" type="hidden" id="lang" value="<?php echo $_GET['lang']; ?>" />
</span>Page Title:</th>
<td class="WADADataTableCell"><input type="text" name="searchtext" id="searchtext" value="" size="32" /></td>
</tr>
</table>
<div class="WADAHorizLine"></div>
<div class="WADAButtonRow">
<table class="WADADataNavButtons" border="0" cellpadding="0" cellspacing="0">
<tr>
<td class="WADADataNavButtonCell" nowrap="nowrap"><input type="image" name="Search" id="Search" value="Search" alt="Search" src="WA_DataAssist/images/Pacifica/Refined_search.gif" /></td>
</tr>
</table>
</div>
</form>
----------------------
And I have copied your code to use the one field;
<?php
//WA Database Search (Copyright 2005, WebAssist.com)
//Recordset: WADApages;
//Searchpage: pages_Search.php;
//Form: WADASearchForm;
$WADbSearch1_DefaultWhere = "";
if (!session_id()) session_start();
if ((isset($_GET["WADbSearch1"])) && ($_GET["WADbSearch1"] != "")) {
$WADbSearch1 = new FilterDef;
$WADbSearch1->initializeQueryBuilder("MYSQL","1");
//keyword array declarations
$KeyArr0 = array("PgTitle");
$KeyArr1 = array("PgDesc");
$KeyArr2 = array("PgDetails");

//comparison list additions
$WADbSearch1->keywordComparison($KeyArr0,"".((isset($_GET["searchtext"]))?$_GET["searchtext"]:"") ."","AND","Includes",",%20","%20","%22","%22",0);
$WADbSearch1->keywordComparison($KeyArr1,"".((isset($_GET["searchtext"]))?$_GET["searchtext"]:"") ."","OR","Includes",",%20","%20","%22","%22",0);
$WADbSearch1->keywordComparison($KeyArr2,"".((isset($_GET["searchtext"]))?$_GET["searchtext"]:"") ."","OR","Includes",",%20","%20","%22","%22",0);

//save the query in a session variable
if (1 == 1) {
$_SESSION["WADbSearch1_search_results"]=$WADbSearch1->whereClause;
}
}
else {
$WADbSearch1 = new FilterDef;
$WADbSearch1->initializeQueryBuilder("MYSQL","1");
//get the filter definition from a session variable
if (1 == 1) {
if (isset($_SESSION["WADbSearch1_pages_Results"]) && $_SESSION["WADbSearch1_search_results"] != "") {
$WADbSearch1->whereClause = $_SESSION["WADbSearch1_search_results"];
}
else {
$WADbSearch1->whereClause = $WADbSearch1_DefaultWhere;
}
}
else {
$WADbSearch1->whereClause = $WADbSearch1_DefaultWhere;
}
}
$WADbSearch1->whereClause = str_replace("\\''", "''", $WADbSearch1->whereClause);
$WADbSearch1whereClause = '';
?>
----------------------

Thanks again,

Chris

It depends on how you are filtering your recordset with the other two form variables

Hi David

Thanks - it gave me a glimmer of hope. Until I tried changing $_GET['SiteID'] to $_POST['SiteID'] in the recordset. Unfortunately, it hasn't made any difference (I have changed the form from GET to POST too).

The three separate fields work fine with the original query, so I can't understand (not being a tecchie!) why the modification doesn't work.

Cheers
Chris

Hi Jason

Third attempt at posting this!

I've just attached the results page, as this has the form on it too.

Many thanks

Chris
