leachus2002 Posted January 24, 2011 Share Posted January 24, 2011 Hi All, I am trying to create a search system - in which part of it I would like to highlight the matched terminology from the relative $_POST value that is coming from the search box. The SQL that I am using to get the query results is: select * from queue where id like '%$searchvalue%' or subject like '%$searchvalue%' or body like '%$searchvalue%' This returns any rows that include like $searchvalue. So if $searchvalue was say "linux" - I would like the code to highlight the word Linux on the page. I am displaying the results on the page using an MSSQL_FETCH_ARRAY, but only displaying the ID and subject fields. Hope that makes sense? Thanks Matt Quote Link to comment https://forums.phpfreaks.com/topic/225475-highlighting-_post-value-in-text/ Share on other sites More sharing options...
dragon_sa Posted January 24, 2011 Share Posted January 24, 2011 you could use str_replace after you get your results like this like this $searchvalue=str_replace("$search" ,"<font color='#FF0000'>$search</font>", $searchvalue); this would then change the color of the variable $search if that represents the word looked for.

codefossa Posted January 24, 2011 Share Posted January 24, 2011 Well, for highlight you would prob wanna use <span style="background-color: #FFFF00">$search</span> instead of font color to make it more of a highlight.

leachus2002 Posted January 24, 2011 Author Share Posted January 24, 2011 Hi dragon_sa, Thanks for that code - however I am finding that it is highlighting the whole line. Let me post my code: $criteria = $_POST ['search_text']; $search_query = mssql_query("select id,subject,body from table where id like %'$criteria'% or subject like %'$criteria'% or body like %'$criteria'%" $show_results = mssql_fetch_assoc ($search_query ){ $show_results['subject']=str_replace("$show_results['subject']" ,"<font color='#FF0000'>$show_results['subject']</font>", $show_results['subject']); echo $show_results['id']; echo $show_results['subject']; echo $show_results['body']; } Cheers Matt Quote Link to comment https://forums.phpfreaks.com/topic/225475-highlighting-_post-value-in-text/#findComment-1164326 Share on other sites More sharing options...
dragon_sa Posted January 24, 2011 Share Posted January 24, 2011 try this $subject=$show_results['subject']; $subject=str_replace($criteria ,"<font color='#FF0000'>$criteria</font>", $subject); echo $subject; Quote Link to comment https://forums.phpfreaks.com/topic/225475-highlighting-_post-value-in-text/#findComment-1164341 Share on other sites More sharing options...
leachus2002 Posted January 24, 2011 Author Share Posted January 24, 2011 Dragon, Awesome! - worked a treat However, I have 1 more question - if I search for "Text" then it will highlight "Text", but not "text". Can this be done? Cheers Matt Quote Link to comment https://forums.phpfreaks.com/topic/225475-highlighting-_post-value-in-text/#findComment-1164353 Share on other sites More sharing options...
QuickOldCar Posted January 24, 2011 Share Posted January 24, 2011 I made a multi-word multi-color highlighter http://dynaindex.com/color-highlighter.php http://www.phpfreaks.com/forums/php-coding-help/highlight-a-word-using-php/msg1516715/#msg1516715 Is 2 diferent functions there at above link, the one i linked is for when are single values in an array, the other function below it is for when need to explode a line a text for the words, exclude anything, and then create the array. You can look there but here's an even newer version of the code I did. function highlighter($words, $content, $backgroundcolors=null, $fontcolors=null) { preg_match_all('~\w+~', $words, $matched); if(!$matched) { return $content; } $words = str_replace(array('+','-'), "", $words); $words = str_replace(" ", "|", $words); $words = trim($words); $words = explode("|", $words); if(is_null($backgroundcolors) || !is_array($backgroundcolors)) { $backgroundcolors = array('yellow', 'red', 'green', 'orange', 'aqua', 'lightskyblue ', 'pink', 'lime', 'fuchsia', 'maroon', 'navy', 'olive', 'purple', 'gray', 'silver', 'teal', 'grey'); if(is_null($fontcolors) || !is_array($fontcolors)) { $fontcolors = array('black', 'white', 'lime', 'oldlace');//change font colors or add more } } $counting = 0; $numbercolors = max(array_keys($backgroundcolors)); foreach ($words as $word) { $word = preg_quote(trim($word)); $content = preg_replace("/\b($word)\b/i", '<span style="border: solid 2px #FFD700; padding: 1px; -moz-border-radius: 5px; -khtml-border-radius: 5px; -webkit-border-radius: 5px; border-radius: 5px; margin: -0; text-align: justify; line-height: 2px; background-color:'.$backgroundcolors[$counting].';font-family:arial;color:'.$fontcolors[$counting].';">\1</span>', $content); if($counting==$numbercolors){ $counting = 0; } else { $counting++; } } return $content; } ?> a simple usage $post_content = highlighter($search_words, $post_content); You can define the colors also, look at examples the demo or codes other forum post. I had css style in this at first in my included stylesheet, then modified the css class into the output themselves. Any time a css class met another class and was a hyperlink there.....it messed up the hyper, was still a pretty color though, so I redid it with good old depreciated basics of font.

dragon_sa Posted January 24, 2011 Share Posted January 24, 2011 this $subject=str_replace($criteria ,"<font color='#FF0000'>$criteria</font>", $subject); would become $subject=str_ireplace($criteria ,"<font color='#FF0000'>$criteria</font>", $subject); this is the case insensitive version Quote Link to comment https://forums.phpfreaks.com/topic/225475-highlighting-_post-value-in-text/#findComment-1164367 Share on other sites More sharing options...
