Hi Freaks I have an update page for an online groundwater information system. I am using Postgresql/PostGIS. This is a screenshot of the update page with 2 select boxes. My problem is I don't want the columns 'well_no' or 'geom' to appear in the first select element, i.e. the column to update, as they should NOT be updated. The code for the first selection drop-down list is as follows: <p> Columns available - select the column to update</p> <form class="my-form" method="post"> <select name='up_column' id='up_column'> <?php try { $result = $pdo->query("select column_name from information_schema.Columns WHERE table_schema = 'public' AND table_name = '{$table}' ORDER BY column_name desc"); foreach ($result as $row) { unset($row['well_no']); unset($row['geom']); echo "<option value={$row['column_name']}>{$row['column_name']}</option>"; } } catch (PDOException $e) { echo "Error: " . $e->getMessage(); } ?> </select> No need to comment that I am not using prepared statements, as I am in a test environment and will rewrite the query before going into production. Please focus on why my use of unset is not working, as both the forbidden columns are appearing in the select list.

I have an existing PHP array ($products) with various fields in it.... id / title / description / link / image link etc. etc. as per requirements for a Google Products feed (https://support.google.com/merchants/answer/7052112). My issue is that, for clothing, Google want a separate record for each size available. My array includes the "size" field as a comma separated list e.g. 6,8,10,12,14 or XS,S,M,L,XL etc. etc. So before creating the feed (a text file, which is currently outputting fine except for the size field issue) I need to duplicate each id where there's more than 1 size in that field, for each size, and then manipulate the fields a little so that (ignoring all the duplicated fields that would remain unchanged) instead of the single record : - id size item group id 52 6,8,10,12,14,16,18,20,22,24,26 I'd have 11 records, item group id would be what the id is, the size appended to the id, and the size field only one (in sequence of those from the original), so: - id size item group id 52-6 6 52 52-8 8 52 . .. ... 52-24 24 52 52-26 26 52 That's just one product....there are quite a lot, each with multiple sizes, but all in the same format within the $products array. As always, any help / pointers / solutions much appreciated!

I have the following function: public function getData($criteria){ $query = "SELECT * FROM {$this->table} WHERE "; $crit = ""; foreach($criteria as $column => $value){ if($column = 'bind'){ $crit .= "{$value} "; }else{ $crit .= "{$column} = {$value} "; } } echo $crit; } I'm testing it with getData(['test1'=>'test2', 'bind'=>'AND', 'test3'=>'test4']); But instead of getting "test1 = test2 AND test3 = test4" the echo output is "test2 AND test4". I'm probably too close to see whats wrong, what do you see?

I have a foreach loop that returns 5 users. I basically want to show only 1 of the 5 users. Every time that loop is run, it should show a random user of the 5, as oppose to the same user every single time. How can that be done? This is my query so far. $find_user = $db->prepare("SELECT user_id FROM users ORDER BY user_id ASC"); $find_user->execute(); $result_user = $find_user->fetchAll(PDO::FETCH_ASSOC); if(count($result_user) > 0) { foreach($result_user as $row) { $user_id = trim($row['user_id']); var_dump($user_id); } }

Say I have the following. record_id | record_name ----------------------------------- 1 one 2 two 3 three 3 three 3 three 4 four 5 five 5 five I want to search through through the table and find all the records. If there are multiple records with same id, I want to combine them into 1 variable and use that. So in the above example, I have 3 threes and 2 fives. I want to combine them so that I only get 1 three and 1 five. How can that be done? A normal query looks like this. $get_records = $db->prepare("SELECT * FROM records"); $get_records->execute(); $result_records = $get_records->fetchAll(PDO::FETCH_ASSOC); if(count($result_records) > 0) { foreach($result_records as $row) { $record_id = $row['record_id']; $record_name = $row['record_name']; } }

I have a questions table and feedback table. I able to foreach the question header but not the feedback. My code as above: <?php $sql2 = "SELECT DISTINCT[question_id],[q_text] FROM [question]"; $ques = array(); $stmt2 = sqlsrv_query($conn, $sql2, $ques); while ($row = sqlsrv_fetch_array($stmt2, SQLSRV_FETCH_ASSOC)) { $ques[$row['question_id']] = $row['q_text']; } $sql = "SELECT [question_id], [Expr3],[Expr2] FROM [feedback] ORDER BY [Expr2] ASC"; $data = array(); $stmt = sqlsrv_query($conn, $sql); while (list($qid, $a, $eid) = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_NUMERIC)) { if (!isset($data[$qid][$eid])) { $data[$qid][$eid] = $newArray2; } $data[$qid][$eid][] = $a; } ?> <div class="container"> <?php // produce table header echo "<table border='1' id='table2excel'>\n"; echo "<tr><th>Employee ID</th>"; // loop over array of questions for the header foreach ($ques as $question) { echo "<th>$question</th>"; } echo "</tr>\n"; foreach ($data as $qid => $question) { foreach ($question as $question => $replies) { echo "<tr><td>$question</td>"; foreach (array_keys($ques) as $q_id) { echo "<td>"; echo $replies[$q_id]; echo "</td>"; } echo "</tr>\n"; echo "</tr>\n"; } } echo "</table>\n"; Questions Table: question_id q_text 1 Do you Like Red Color? 02A Do you Like Yellow Color? 02B Do you Like Blue Color? 3 Do you Like Green Color? 4 What color you like among them? 5 Do you Like Purple Color? 6 Do you Like Gold Color? 7 Do you Like Rose Gold Color? 8 Do you Like Black Color? 9 Do you Like Orange Color?

Hi, guys i'm trying to fetch all results from DB through a foreach loop. But it is not working as intended, as it brings only the first record and not the others. here is my code:- $sql1="select * from group_posts"; $stmt_t=$conn->prepare($sql1); $stmt_t->execute(); $data_fetch=$stmt_t->fetchAll(); foreach ($data_fetch as $row_d) { $postid=$row_d['gp_id']; $post_auth=$row_d['author_gp']; $post_type=$row_d['type']; $post_title= html_entity_decode($row_d['title']); $post_data= html_entity_decode($row_d['data']); $data1= array($post_data); // $data1= taggingsys($data0); $post_date=$row_d['pdate']; $post_avatar=$row_d['avatar']; $post_uid=$row_d['user_id']; if ($post_avatar != ""){ $g_pic='user/'.$post_uid.'/'.$post_avatar; } else { $g_pic='img/avatardefault.png'; } $user_image="<img src='{$g_pic}' alt='{$post_auth}' title='{$post_auth}' width='30' height='30'>"; $vote_up_count=$project->voteGroupCheck($postid, $_SESSION['id']); }

Hello. Just a quick question about using a loop to create a string from post variables that will then be used in a query. I have several post variables submitted in a form, some of which contain a value of T. Others are not selected. In the database there are several columns which may contain values of T or may not. I would like to construct a query that searches for specific columns containing T and ignoring the rest. I'm using WHERE "T" IN(colnames). I need to get the column names into a comma separated string. Here's what I'm using: $postVal = array("1", "2", "3", "4", "5"); foreach ($postVal as $key=>$val){ $newVar = “col”.$val; if ($$newVar == "T") { *create/add to comma-separated string } else { *ignore } } I hope that seems clear enough. I'm just not sure if I'm on the right track or not. What do you think? Thank you, in advance!

I have the following in a form that edits values already put into a dbase. $alev = array(1 => '1', 2 => '2', 3 => '3', 4 => '4', 5 => '5', 6 => 'AP'); $dblev = explode(',',$row['hw_lev']); foreach ($alev as $key => $lev){ if(in_array($lev,$dblev)){ echo "<input type='checkbox' name='ud_lev[]' value='$lev' checked> $lev"; } else { echo "<input type='checkbox' name='ud_lev[]' value='$lev'> $lev"; } When I attempt to edit the dbase values, the following occurs: When I select the "A" checkbox, it is input into the database and reflects in the results. When I attempt to edit this, the "A" box is checked and all is well. When I select anything else AND "A" ("1", "A"), it is input into the database and reflects in the results. When I attempt to edit this, the "1" box is checked but the "A" box is NOT checked. This is what I need. I feel like the problem is with the array? But it could be the loop.. Probably something totally staring me in the face. You know how it goes. I was wondering if you see a problem in the array or in the loop. Any thoughts would be appreciated!

Here's what I'm trying to do. I retrieve results using php foreach loop. Within that loop results, I want to show a div(.show-details) on mouse over only. How do I do that? This is my code so far. <style> .show-details { display: none; } </style> $get_records = $db->prepare("SELECT * FROM records WHERE record_id = :record_id"); $get_records->bindParam(':record_id', $record_id); $get_records->execute(); $result_records = $get_records->fetchAll(PDO::FETCH_ASSOC); if(count($result_records) > 0){ foreach($result_records as $row) { $get_record_title = $row['record_title']; $get_record_details = $row['record_details']; $get_record_price = $row['record_price']; ?> <div class="product"> <div class="product-title"> <?php echo $get_record_title; ?> </div> <div class="product-price"> <?php echo $get_record_price; ?> </div> </div> <div class="show-details"> <?php echo $get_record_details; ?> </div> <?php } } else { echo 'no results.'; } <script> $(document).ready(function() { $(".product").mouseover(function(){ $(".show-details").css("display", "block"); }); }); </script>
