RE: [PHP-DB] Multiple work mySql database search.
Or even better :
Try this :
$string = "Hello World";
$TableName = "Table";
$FieldName = "Field";
$Field = "CONCAT_WS('', ' ', TRIM($TableName.$FieldName), ' ')";
$Op = $Type=="All" ? "AND" : "OR";
$where = "WHERE ($Field LIKE '% ".(preg_replace("/[\s]+/", " %' $Op $Field
LIKE '% ", $string))." %')";
$sql = "SELECT * FROM Table ". $where;

Join them either with ANDs or ORs like this:
Searching for all words in a field: WHERE (field LIKE '%something%
AND field LIKE '%other_thing')
Searching for any of the words in a field: [read above in the
previous question]

Re: [PHP-DB] Multiple work mySql database search.
Split your phrase with split or explode functions.
Then implode the new array as something like 'i', 'want', 'to', 'search' from 'i want
to search'.
Then create your whereClause for each of the result. If you want to find exactly the
words than you might use the IN keyword.. like SELECT * FROM table WHERE word IN ('i',
'want', 'to', 'search').

Subject: [PHP-DB] Multiple work mySql database search.
Hi all you experts who have help me often in the past, may I now ask
what is probably so simple for someone doing PHP everyday...
I have a product database which can be searched for a keyword in up to 3
fields; using this select query:
$sql_select = "SELECT * from productlist WHERE (Name LIKE
'%$SearchText%') OR (Description LIKE '%$SearchText%') OR (Keywords LIKE
'%$SearchText%') ORDER BY Name";
What I really want to achieve is if someone enters more than one work in
the search for, how can I get the select query to search for one, the
other, or both?
I've thought of putting an option on the search for the user to select
'All Words' or 'Any Word' so that the select query could deal with the
search based on the full phrase they entered or any of the words.
My problem is how to build the query.
Any help would be massively appreciated.
Martin
