PHP - Php Mysql Search With Checkboxes
having a small issue setting up a search, trying to use check boxes, here is my form code
<form action="workorder_index.php" method="POST"> <input type="checkbox" name="wos_0" <? if($wos_0 != NULL) { echo "checked"; }?>>0 - Active <input type="checkbox" name="wos_1" <? if($wos_1 != NULL) { echo "checked"; }?>>1 - Completed awaiting pickup <input type="checkbox" name="wos_2" <? if($wos_2 != NULL) { echo "checked"; }?>>2 - Completed and out the door <input type="checkbox" name="wos_3" <? if($wos_3 != NULL) { echo "checked"; }?>>3 - Waiting call back <input type="checkbox" name="wos_4" <? if($wos_4 != NULL) { echo "checked"; }?>>4 - Waiting for parts<br> <input type="checkbox" name="wos_5" <? if($wos_5 != NULL) { echo "checked"; }?>>5 - Parts in waiting for completion <input type="checkbox" name="wos_6" <? if($wos_6 != NULL) { echo "checked"; }?>>6 - not used <input type="checkbox" name="wos_7" <? if($wos_7 != NULL) { echo "checked"; }?>>7 - Overdue for pickup <input type="checkbox" name="wos_8" <? if($wos_8 != NULL) { echo "checked"; }?>>8 - Scrapped per customer <input type="checkbox" name="wos_9" <? if($wos_9 != NULL) { echo "checked"; }?>>9 - Scrapped by overdue<br><br> <input type="hidden" value="1" name="customsearch"> <input type="Submit" value="Update"> </form> here is my handling code $wos_0=$_POST[wos_0]; $wos_1=$_POST[wos_1]; $wos_2=$_POST[wos_2]; $wos_3=$_POST[wos_3]; $wos_4=$_POST[wos_4]; $wos_5=$_POST[wos_5]; $wos_6=$_POST[wos_6]; $wos_7=$_POST[wos_7]; $wos_8=$_POST[wos_8]; $wos_9=$_POST[wos_9]; if(isset($_POST['customsearch'])) { $str=''; if($wos_0 != NULL) { $str.= "'0'"; } if($wos_1 != NULL) { $str.= ",'1'"; } if($wos_2 != NULL) { $str.= ",'2'"; } if($wos_3 != NULL) { $str.= ",'3'"; } if($wos_4 != NULL) { $str.= ",'4'"; } if($wos_5 != NULL) { $str.= ",'5'"; } if($wos_6 != NULL) { $str.= ",'6'"; } if($wos_7 != NULL) { $str.= ",'7'"; } if($wos_8 != NULL) { $str.= ",'8'"; } if($wos_9 != NULL) { $str.= ",'9'"; } $query="SELECT * FROM workorders a INNER JOIN customers b ON a.customer_id = b.customer_id WHERE a.workorder_status IN (".$str.")

I want to do a database query like this, if firstname is checked, and gender is checked. I want to find someone in the database with that gender and first name only. If all of them are checked, find all matches to that criteria. I think this might be a lot harder than I describe, but that is what I need to do. like this Code: [Select] mysql_query("SELECT users WHERE gender LIKE '%gender%, OR firstname LIKE....." Code: [Select] Search the database by: <form action="search.php" method="post"> <p> <input type="checkbox" name="firstname2" size="20" id="firstname2" value="firstname2" /> First Name<br/> <input type="checkbox" name="lastname2" size="20" id="lastname2" value="lastname2" /> Last Name<br/> <input type="checkbox" name="dob2" size="20" id="dob2" value="dob2" /> Date of Birth<br/> <input type="checkbox" name="gender2" size="20" id="gender2" value="gender2" /> Gender<br/> <input type="submit" name="search" value="Search" /> <input type="reset" name="reset" value="reset" /> </form> Hopefully someone can help me before I run to the top of a bell tower Okay, so aside from the dramatics, total noob here, playing around with PHP/Jquery/mySQL. I'm trying to search a database using three checkboxes, these are keywords that are sent via Jquery to a php file where i'll do a search against the database and throw back any articles that match the keyword. The Jquery/Form part is working, i'm just a little lost (to say the least) on where to go in the PHP end of things. I'm following Learning PHP and MySQL by O'Reilly but I'm stuck here. So the form looks like this: Code: [Select] <form id="findkeywords"> <ul> <li><input type="checkbox" name="keywords[]" value="keyword1" title="keyword1" /></li> <li><input type="checkbox" name="keywords[]" value="keyword2" title="keyword2" /></li> <li><input type="checkbox" name="keywords[]" value="keyword3" title="keyword3" /></li> <li><input type="submit" name="submit" class="search" /></li> </ul> </form> The jQuery that passes the checkboxes to the php file is as follows: Code: [Select] <script type="text/javascript"> $(document).ready(function(){ $(".search").click(function() { $.post("parser2.php", $("form#findkeywords").serialize(), function(data) { $.each(data, function() { $("div#result").append("<li class='arrow'><a href='parser2.php?id=" + this.id + "'>" + this.title + "</a></li>"); }); $("div#jsonContent").show(); }); }); }); </script> Ok, so the trouble comes here, I want to take the checked boxes into the PHP file through $_POST, check for articles with the keywords and return them to the jQuery to be displayed, works fine with a simple 'type in and search', but I just can't get my head around the checkboxes. The (horrid) code: Code: [Select] $link = mysql_connect("localhost","root","root"); mysql_select_db("keyworddb", $link); foreach($_POST['keywords'] as $keyword => $value) { $query = mysql_query("SELECT * FROM articles WHERE keyword LIKE '%". $value ."%' "); $arr = array(); while( $row = mysql_fetch_array ( $query ) ) { $arr[] = array( "id" => $row["id"], "title" => $row["title"] ); } echo json_encode($arr); } Any ideas? What am I doing so horribly wrong (apart from everything in parser2.php ) Thanks! Need some help I have 2 tables in a database and I need to search the first table and use the results from that search, to search another table, can this be done? and if it can how would you recommend that I go about it? Thanks For Your Help Guys! The result pages is supposed to have pagination like google help me please
Hey everyone. [= I don't have much time to read through all of the forums, because I'm on a time crunch and I'll be putting this certain project behind a couple others while I wait for some answers. This project is confusing me a bit, because I haven't worked much with arrays and the good ol' checkbox, so I need some help getting this to work. This project requires me to set-up a checkbox next to each order that was pulled off a database. You are allowed to select as many checkboxes as you'd like, and then click on the "process receipts" for all of the orders that were selected. I need to be able to have the form send me straight to a new page that pulls a loop of receipts one after another. I have the receipts built, and I can access a receipt one at a time based off the ID of a certain order, and I can easily build a loop that presents the receipts. I'm just having a problem pulling the information off the database based from the checkbox array. If you can give me some ideas on where to start with this, I'd greatly appreciate it. Note: Example is inside a hidden administrative page. Can't really give you something to play with, sorry! QQ Thanks! Alex D.A. Designing I was fiddling around with php and concerning data in a mysql database. All I was wanting to understand was being able to remove values with cheking multiple items in outputted html list. One that reads a set of values from a database, then displays a check box allowing the user to delete such values, that's it basically, here is my script I used to do it: Code: [Select] <?php function deleteRow($value) { $sql = "DELETE FROM checkbox WHERE value LIKE '$value'"; $result = mysql_query($sql); } if(array_key_exists('delete', $_POST)){ if(isset($_POST['value'])) { $count = count($_POST['value']); $connect = mysql_connect('localhost', 'jeremy', 's56pj989'); if($connect) { $select_db = mysql_select_db('test'); if($select_db) { for($i=0; $i<$count; $i++){ // print 'This is item = '.$_POST['value'][$i]; // outputs fine if(strlen($_POST['value'][$i]) > 0) { deleteRow($_POST['value'][$i]); } } } } } } ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head> <title></title> </head> <body> <form id="myform" name="myform" action="<?=$_SERVER['PHP_SELF']; ?>" method="post"> <?php if($_SERVER['REMOTE_ADDR'] == '192.168.0.2') { // printf("<p>Yes you have connected to this script successfully!</p>"); $connect = mysql_connect('localhost', 'mydbuser', 'mydatabasepassword'); if($connect) { // printf("<p>You have now connected to the database, well done!</p>"); $select_db = mysql_select_db('test'); if($select_db) { // printf("<p>Selected database now</p>"); $sql = 'SELECT * FROM checkbox'; $result = mysql_query($sql); if($result) { if(mysql_num_rows($result)>0){ while($row = mysql_fetch_assoc($result)) { printf("%s <input type=\"checkbox\" name=\"value[]\" value=\"%s\">\n<br />\n", $row['value'], $row['value']); } } else { printf("<p>No rows in system!</p>"); } } } } } ?> <input type="submit" id="delete" name="delete" value="Delete" /> </form> </body> </html> There must be a better way shouldn't there? I am not too concerned with error checking, ie if result of removing the values doesnt work, since I will just use this as an example of how to do this. Going on from that, how would I allow it to update a set of say changed values, just purely out of interest, pretty happy since it works though this script. But I was also wondering if there's some easy way of updating a set of values perhaps? Hmm good though and I look forward to any replies, Jeremy. Hi all How do I modify the below code to search multiple tables in mySQL database? $query = "select * from store_items where description like \"%$trimmed%\" or title like \"%$trimmed%\" or dimensions like \"%$trimmed%\" order by id ASC"; $numresults=mysql_query($query); $numrows=mysql_num_rows($numresults); It is for a search function and I need it to search another table called 'about_text' and 'faq_text' Thanks Pete I built a series of insertion forms to put entries into a mysql database. Everything is working fine, except that I just now realized my checkboxes don't put any entry in. It's just leaving it's respective smallint field as a default "0". Being new, I've must've overlooked how to handle these. The form's checkboxes have a bit of code in the value that remembers what users chose in case they have to backtrack and redo their form. How would I solve the problem and keep this code? Here's what all the checkboxes are written like: Code: [Select] <input type="checkbox" name="green_leaf" value="<?php if(isset($_POST['1'])) echo $_POST['1']; ?>" > green Hey all... I'm running into a problem here. If you take a look at the code for this, you'll see it's to enter "horses" into a "class." It's all fine and dandy except I'm trying to get the way the horses are selected to have a different option. Right now they exist as a drop down/select option where you have to choose one at a time and enter submit. My goal is to have checkboxes that users can toggle and submit them all at once (with the rest of the eligibility checks etc still applicable). I've looked it up and the problem is, each user has a different amount of horses, so I can't account for all of them manually. Could someone help me out? On DaniWeb a user was trying to help me with an implode option, but I have zero idea how to work with that. I will literally need my hand to be held through this one. Thank you in advance - I have been trying to do this myself for a good chunk of the day, but my PHP skills are quite limited. Code: [Select] <?php session_start(); // Maintain session state header("Cache-control: private"); // Fixes IE6's back button problem. $page_title = "Class Information"; include('header.php'); $class_id = $_GET['id']; $enter = $_POST['enter_horse']; $enter_check = $_POST['check']; $horse_id = $_POST['horse_id']; //general show information $result = @mysql_query("SELECT s.show_id, s.player_id, s.type, s.name, DATEDIFF(s.run_date, NOW()) AS datedif, c.class_id, s.entry_fee FROM classes c, shows s WHERE c.class_id='$class_id' AND c.show_id=s.show_id LIMIT 1")or die("Cannot find class!

What I am trying to do is have a checkbox next to each user (row) that when I check them and hit submit at the bottom, it will change the value of each row on the 'Closed' column to 'y' so it will not be displayed when the page is refreshed. I want to be able to select multiple items to "close". And I would like it to come back to this page. I think I can use this page as the form action and have the code above my while loop to change the Closed column so it then would not be displayed when the while loop is called... is that right? How do I set this up? Not sure where to start the form tag and where to end it, and not sure how to...well...do any of it. I have a table in a mysql database with 5 columns, id, Name, Wifi, Bluetooth, GPS, with rows that are for example 1, Galaxy S2, yes, yes, yes. So basically i want to build a form that has check boxes (3 checkboxes for wifi bluetooth and GPS respectively) that once selected will query the database depending on which check boxes are selected. I have made the form but need to know what to put in the filter.php to make the results be displayed accordingly. Ideally if anyone knows how i would want it so the results were shown on the same page which i believe u need to use ajax to happen but any help on how to show the results will be greatful. the code for the form i have made is as follows: Code: [Select] <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title> </head> <body> <form action="filter.php" method="post"> <INPUT TYPE=CHECKBOX NAME="option[]" VALUE="Wifi" id="r1">Wifi <INPUT TYPE=CHECKBOX NAME="option[]" VALUE="Bluetooth" id="b1">Bluetooth <INPUT TYPE=CHECKBOX NAME="option[]" VALUE="GPS" id="g1">GPS <input type="submit" name="formSubmit" value="Submit" /> </form> </body> </html> im not sure on how to make the filter.php page but i do have this code for displaying the all the data but i want to kno how to make it only display the data from the choices on the checkboxes Code: [Select] <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>pls work</title> </head> <body> <?php function h($s) { echo htmlspecialchars($s); } mysql_connect("localhost", "root", "") or die (mysql_error()); mysql_select_db("project") or die (mysql_error()); $result= mysql_query('SELECT * FROM test') or die('Error, query failed'); ?> <?php if (mysql_num_rows($result)==0) { ?> Database is empty <br/> <?php } else { ?> <table> <tr> <th></th> <th>Name</th> <th>Wifi</th> <th>Bluetooth</th> <th>GPS</th> </tr> <?php while ($row= mysql_fetch_assoc($result)) { ?> <tr> <td> <a href="uploaded-images/<?php h($row['Name']); ?>.jpg"> <img src="uploaded-images/<?php h($row['Name']); ?>.jpg" alt="test"/> </a> </td> <td><a href="textonly.html"><?php h($row['Name']); ?></a></td> <td><?php h($row['Wifi']); ?></td> <td><?php h($row['Bluetooth']); ?></td> <td><?php h($row['GPS']); ?></td> </tr> <?php } ?> </table> <?php } ?> </body> </html> Hi people. I have a form which inputs into a database. Here is the code that inserts a yes no option... Code: [Select] <select name = "consent"> <option value = "Yes" <?php if ($_POST['consent'] == 'Yes') { echo 'selected="selected"'; } ?>>Yes</option> <option value = "No" <?php if ($_POST['consent'] == 'No') { echo 'selected="selected"'; } ?>>No</option> </select> However, I have been asked if I can make it a yes or no checkbox instead. Please can you tell me how I need to code it so that the "yes" or "no" is recorded in the DB. At the moment I just have this Code: [Select] <input name="consent" type="checkbox" value="Yes" />Yes<br /> <input name="consent" type="checkbox" value="No" />No<br /> Thanks in advance VinceG I have figured out far enough to loop through my table and return a list of check boxes that will be matched to a product. My issue now, is i cannot figure out the proper way to loop through them after they are selected and return them as checked/unchecked for the given product. Thought there is some MySQL involved, that part isn't the problem, I know how to insert into a database or update...when the product is selected from a drop down, I need to be able to populate the checkboxes. Here is the code i am using to initially display all of the categories to choose from... <ul class="categories"> <?php $query = "SELECT * FROM products"; $result = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_assoc($result)) { $category = $row['category']; $catId = $row['id']; echo "<li><input class='catCheck' type='checkbox' name='p_cat[]' value='$catId' /> $category</li>"; } ?> </ul> Thanks guys.... Hi, I am having difficulty deleting rows in my table using check boxes. I have all the check boxes displaying for each row and a delete button below the table. However when i click on the delete button it isnt deleting the checked rows, i have displayed the code below that i am using; Code: [Select] <?php $result = mysql_query("SELECT * FROM contact ORDER BY msg_id ASC"); echo "<table border='1'> <tr> <th>Delete</th> <th>Message ID</th> <th>Name</th> <th>Email</th> <th>Message</th> </tr>"; while($row = mysql_fetch_array($result)) { ?> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<?php echo $row['del_id']; ?>"></td> <?php echo "<td>" . $row['msg_id'] .

As result/row is retuned to the user i would like to be able to detect whether or not they have checked a checkbox at the end of each rown in which case multiple rows can then be deleted from the database upon the user clicking a 'delete multiple records' button. I have no problem in being able to display the checkboxes on the webpage but i am a little unsure as to how to refernce them and detect which ones the user has checked. Given my database stores hostnames/IP addresses would it be best to name each checkbox to reflect the hostname or name the value it returns when checked to reflect the hostname. Given the above and that I also store the results of a users search in a $_SESSION['hosts'][][] array how can I then tie the two together? Thanks for reading. Hello friends,
I am a novice in php. Though I create 2 scripts:
1. students registration form
2. search students by Registration Number
Our students' Registration Numbers are as follows: nifeA001, nifeA002 & so on...
But when someone enter just "nife" or "n" or "A" etc all the students's data is showing.
I want that students can search data by entering only Full Registration Number not a Part.
I am placing the search.php code below. Please help me out....
----------------- Search.php ------------------
<?php
mysql_connect("localhost", "root", "") or die("could not connect");
mysql_select_db("student") or die("could not connect");
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
$searchq = preg_replace("#[^0-9a-z]#i", "", $searchq);
//here
$query = mysql_query("SELECT * FROM user WHERE registration LIKE '%$searchq%'") or die("could not search!");
$count = mysql_num_rows($query);
if($count == 0){
$output = 'There was no search results!';
}else{
while($row = mysql_fetch_array($query)) {
$fname = $row['firstname'];
$lname = $row['surname'];
$id = $row['registration'];
$output .= '<div> '.$id.' '.$fname.' '.$lname.'</div>';

Edited by NasimUddinAhmmad, 13 January 2015 - 05:43 AM. Hello I wonder if it is possible to make a search form with different fields where all conditions should be met if the field is set. I have this code: $sel = "SELECT * FROM database "; $sel .= "WHERE ((test1 = '$test1' "; $sel .= "AND test2 = '$test2' "; $sel .= "AND test3 = '$test3' "; $sel .= "ORDER BY id "; $query = mysql_query($sel) or die(mysql_error()); if (mysql_num_rows($query) == 0){ echo ("No result"); exit; When I use this and leave for example 1 field empty I get the error: No result. Is it possible to make smothing so the condition only should be met if the field is set? So If test1 and test3 are set these condition should be met.. I hope you can help! Thanks in advance! - Frederik I found an article on how to implement a mysql search (http://www.iamcal.com/publish/articles/php/search/) and it seemed like a good way to go, but I can't get it up and running. Here is my code: Code: [Select] <?php $db_host = 'localhost'; $db_user = 'username'; $db_pwd = 'password'; $database = 'dbname'; $table = 'Principals'; if (!mysql_connect($db_host, $db_user, $db_pwd)) die("Can't connect to database"); if (!mysql_select_db($database)) die("Can't select database"); $searchterms = 'dorr oliver'; function search_split_terms($terms){ $terms = preg_replace("/\"(.*?)\"/e", "search_transform_term('\$1')", $terms); $terms = preg_split("/\s+|,/", $terms); $out = array(); foreach($terms as $term){ $term = preg_replace("/\{WHITESPACE-([0-9]+)\}/e", "chr(\$1)", $term); $term = preg_replace("/\{COMMA\}/", ",", $term); $out[] = $term; } return $out; } function search_transform_term($term){ $term = preg_replace("/(\s)/e", "'{WHITESPACE-'.ord('\$1').'}'", $term); $term = preg_replace("/,/", "{COMMA}", $term); return $term; } function search_escape_rlike($string){ return preg_replace("/([.\[\]*^\$])/", '\\\$1', $string); } function search_db_escape_terms($terms){ $out = array(); foreach($terms as $term){ $out[] = '[[:<:]]'.AddSlashes(search_escape_rlike($term)).'[[:>:]]'; } return $out; } function search_perform($terms){ $terms = search_split_terms($terms); $terms_db = search_db_escape_terms($terms); $terms_rx = search_rx_escape_terms($terms); $parts = array(); foreach($terms_db as $term_db){ $parts[] = "Principals RLIKE '$term_db'"; } $parts = implode(' OR ', $parts); $sql = "SELECT * FROM Principal WHERE $parts"; $rows = array(); $result = mysql_query($sql); while($row = mysql_fetch_array($result, MYSQL_ASSOC)){ $row[score] = 0; foreach($terms_rx as $term_rx){ $row[score] += preg_match_all("/$term_rx/i", $row[Principals], $null); } $rows[] = $row; } uasort($rows, 'search_sort_results'); return $rows; } function search_rx_escape_terms($terms){ $out = array(); foreach($terms as $term){ $out[] = '\b'.preg_quote($term, '/').'\b'; } return $out; } function search_sort_results($a, $b){ $ax = $a[score]; $bx = $b[score]; if ($ax == $bx){ return 0; } return ($ax > $bx) ? -1 : 1; } function search_html_escape_terms($terms){ $out = array(); foreach($terms as $term){ if (preg_match("/\s|,/", $term)){ $out[] = '"'.HtmlSpecialChars($term).'"'; }else{ $out[] = HtmlSpecialChars($term); } } return $out; } function search_pretty_terms($terms_html){ if (count($terms_html) == 1){ return array_pop($terms_html); } $last = array_pop($terms_html); return implode(', ', $terms_html)." and $last"; } # # do the search here... # $results = search_perform($searchterms); $term_list = search_pretty_terms(search_html_escape_terms(search_split_terms($searchterms))); The table name is 'Principals' and the field name I am trying to search is 'Principal'. I am getting an error on the line: while($row = mysql_fetch_array($result, MYSQL_ASSOC)){ The error is: Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource Can anyone shed some light on this for me? |
