Wanted to get 2 values id and name but im confuse how get it, i wanted to show the id in the link. heres the sample code.
echo "<table width=\"100%\" border=\"1\" cellpadding=\"5\" cellspacing=\"2\" bordercolor=\"#FFFFFF\">";
$count = 1;
$id=$_GET['id'];
$col1 = $col2 = array();
$rowcount = round(mysqli_num_rows($nquery) / 2);
while($crow = mysqli_fetch_assoc($nquery)) {
if($count > $rowcount) $col2[] = $crow['title'];
else $col1[] = $crow['title'];
$count++;
}
$counter = 0; // Arrays start with 0
foreach($col1 as $crow) { // $col1 will always be >= $col2
$row2 = (isset($col2[$counter])) ? $col2[$counter] : "";
echo "<tr><td><a href='index.php?page=".$id."'>" . $crow . "</td><td>" . $row2 . "</td></tr>";
$counter++;
}
echo "</table>";
?>`
id wont show up on the link. Hope someone can help. Thanks
You're trying to get $id values from the query string (that's what the $_GET superglobal is) and not from the database.
If both elements (ID and name) are coming from the same database query, you may try something like this:
$crow = mysqli_fetch_assoc($nquery);
foreach ($crow as $row)
{
echo $row['id'].' is the ID and '.$row['title'].' is the title';
}
if you remain within the foreach loop, you can use $row['id'] and $row['title'] to build the table element and link you're trying to obtain.

I am trying to pull data from a table in PHPmyadmin and convert it to an HTML table based on some customer form input which filters out unneeded rows. The code below does that fine. The issue is that two of my columns need to contain links.
It would be easy enough to use PHP to change the table data into the link using a strtolower() and str_replace() to remove spaces, then concatinating the "www.website.com/" and the ".html". But I'm using a foreach loop to get all of the rows that I need and I don't know how to only alter one value per row.
I have tried using "Broswer Display Transformations" and "Input Transformations" in PHPmyadmin, but that only seems to affect the data in PHPmyadmin and not when I access the data via PHP.
My current code:
//* Code for Table
$query = "SELECT $searchFields FROM `hose_reels` $searchPhrase ORDER BY `model` ASC";
$result = mysqli_query($cxn,$query);
if ($row[$key] != "0") {
echo '<table width="100%" border="1" class="table"><tr>';
$row = $result->fetch_assoc();
foreach ($row AS $key => $value) {
$key = ucwords(str_replace('_', ' ', $key));
echo "<th>" . $key . "</th>";
}
echo "</tr>";
$result2 = mysqli_query($cxn,$query);
while($row = $result2->fetch_assoc()) {
echo "<tr>";
foreach ($row AS $key => $value) {
$row['$key'] = $value;
echo "<td>$row[$key]</td>";
}
echo "</tr>";
}
echo "</table>";
}
else {
echo "<p>No results match your selection. Please broaden your search.</p>";
}
Just add <a> tag in your php code. Below is the code. One more thing you have error in echo "<td>$row[$key]</td>"; line . it prints <td>$row[$key]</td> not the result you are fetching from DB.
echo '<table width="100%" border="1" class="table"><tr>';
$row = $result->fetch_assoc();
$i = 1;
foreach ($row AS $key => $value) {
$key = ucwords(str_replace('_', ' ', $key));
if($i == 1 || $i ==3){
echo "<th><a href='".key ."'" . $key . "</a></th>";
}else{
echo "<th>" . $key . "</th>";
}
$i++;
}
echo "</tr>";
$result2 = mysqli_query($cxn,$query);
$j =1;
while($row = $result2->fetch_assoc()) {
echo "<tr>";
foreach ($row AS $key => $value) {
$row['$key'] = $value;
if($i == 1 || $i ==3){
echo "<td><a href='".$row[$key]."'".$row[$key]."</a></td>";
}else{
echo "<td>$row[$key]</td>";
}
}
echo "</tr>";
}
echo "</table>";
I'm trying to display all the information in a msSQL table in an HTML table and have up with something that is not so great.
<table border="1">
<?
echo "<tr>";
for ($i = 0; $i < mssql_num_fields($result); ++$i){
echo "<th>" .$column_names[$i] . "</th>";
}
echo "</tr>";
$num_rows = mssql_num_rows($result);
for ($i = 0; $i < $num_rows; ++$i){
echo "<tr>";
foreach ($column_names as $key => $val){
$result_row = mssql_query("SELECT * FROM username WHERE id = '$i'");
$row = mssql_fetch_assoc($result_row);
echo "<td>";
echo $row[$val];
echo "</td>";
}
echo "</td>";
}
?>
</table>
This works. The first part prints out the column names successfully, but as for the rest:
1) I think it is sort of cumbersome to make a query for every time through the loop
2) it doesn't really work because the ids of the rows go much higher than the number of rows in the table, as some ids aren't used.
It seems like I should be able just make one query and pull everything from the database at one go, then build my HTML table from that, but I can't figure out how to access it row by row where I could go $row[next row][shifted value from $column_names. How can improve this query?
function table_cell($item, $header=false) {
if (!$item) return '';
$elemname = ($header) ? 'th' : 'td';
$escitem = htmlspecialchars($item, ENT_NOQUOTES, 'UTF-8');
return "<{$elemname}>{$escitem}</{$elemname}>";
}
function table_header_cell($item) {
return table_cell($item, true);
}
function table_row($items, $header=false) {
$func = ($header) ? 'table_header_cell' : 'table_cell';
return "<tr>\n\t".implode("\n\t", array_map($func, $items))."\n</tr>\n";
}
function echo_result_as_table($result) {
if ($result && $row = mssql_fetch_assoc($result)) {
$columnnames = array_keys($row);
echo "<table>\n", table_row($columnnames, true), "\n";
do {
echo table_row($row), "\n";
} while ($row = mssql_fetch_assoc($result));
echo "</table>\n";
}
}
$result = mssql_query("SELECT * FROM username");
echo_result_as_table($result);
if ($result) mssql_free_result($result);
If you have an array of associative arrays instead of a raw mssql result handle, you can use a function like this to produce a table string:
function array_to_table($arrayofassoc) {
if (!$arrayofassoc) return '';
$tablestr = '<table>';
$tablestr .= table_row(array_keys($arrayofassoc[0]), true);
$tablestr .= implode('', array_map('table_row', $arrayofassoc));
$tablestr .= '</table>';
return $tablestr;
}
try this:
while($row = mysql_fetch_results($result)){
echo '<td>'.$row['column_name'].'</td>';
}
with 'column_name' being the name of the column in mysql.
but some will say..."wait, but PDO"
I'm working on an online menu ordering system and I wanted to filter the data according to its category. I've tried to make it work with this code but it's only displaying one category.
**<li><?php echo "<a href='clubmarumenu.php?choice=".$category."'>"?> Scotch/Bourbon</a></li>
<li><?php echo "<a href='clubmarumenu.php?choice=".$category."'>"?> Brandy/Cognac</a></li>

I wish I could get over this wall. Please help~
First things first.
<?php echo "<a href='clubmarumenu.php?choice=".$category."'>"?>
In the first chunk of code, you are using the same variable for all the links.
Are you passing different values for $category here. I believe you are not! and hence all the links are pointing to the same url.
You should use urldecode instead of str_replace('%', ' ', $category). (http://in2.php.net/urldecode)
Please indent your code so that it can be read and understood easily :)
My query etc is working perfectly fine, but I am unable to get an added total of the results in a variable to echo out.
With what I have below, I keep getting a 0 (zero) amount in the $full_total; value.
while($row = mysql_fetch_array($all_donations)) {
$donation_date = date("m/d/Y", $row['date']);
echo "<tr><td>" . $donation_date ."</td><td>" . number_format($row['price'], 2) ."</td></tr>";
$total_dontations = number_format($row['price'], 2);
$full_total += $total_donations;
}
// echo this amount outside of the loop.
echo $full_total;
Try initializing full_total
$full_total = 0;
while($row = mysql_fetch_array($all_donations)) {
//...
Try defining $full_total above the your while statement like this:
$full_total = 0;
while($row = mysql_fetch_array($all_donations))
{ ...
I think its similiar with Using a variable outside of the while loop (scope)
According that thread, you can go like this
$full_total = "";
while($row = mysql_fetch_array($all_donations)) {
$donation_date = date("m/d/Y", $row['date']);
echo "<tr><td>" . $donation_date ."</td><td>" . number_format($row['price'], 2) ."</td></tr>";
$total_dontations = number_format($row['price'], 2);
$full_total += $total_donations;
}
// echo this amount outside of the loop.
echo $full_total;
I have a nested array grouping three other arrays: $online, $busy and $offline, in order to display results in this exactly order.
$conteudo = array($online, $ocupado, $offline);
The desired result would be a table in two columns to display results in continuous flow like this:
online1 | online2
online3 | busy1
busy2 | offline1
offline2| offline3
offline4|
I've been trying lots of foreach loops and playing around changing the html tags, but the closest I can arrive of the desired result is this:
<table width='100%' cellpadding='5' border="1">
<?php
$i = 1; //contador de colunas
$max_colunas = 2; // numero de colunas
foreach ($conteudo as $row) {
echo "<tr>";
foreach ($row as $col) {
foreach ($col as $cell) {
if ($i == 1) {
echo "<td>" . $cell . "</td>";
} elseif ($i == $max_colunas){
echo "<td>" . $cell . "</td></tr>";
$i = 0;
} else {
echo "<td>" . $cell . "</td>";
}
$i++;
}
}
echo "</tr>";
}
This code will output a table like this:
onine1 | online2 |online3
busy1 | busy2 |
offline1|offline2 |offline3|offline4
I can't find out why it ignores completely $max_colunas, seems like it prints all the elements inside the array in row.
If I remove lines:
echo "<tr>";
echo "</tr>";
from beginning and end of foreach it will output all in a row like this:
onine1 | online2 |online3 | busy1 | busy2 |offline1|offline2 |offline3|offline4
Any suggestions to get the desired output format will be so appreciated.
Edited on 17/01:
This is how I'm getting the arrays from:
//group people
$online = array(); //group online
$ocupado = array(); //group ocupado
$offline = array(); //group offline
//select people to group
$atendentes = mysql_query("SELECT nome FROM atendentes ORDER BY nome") or die(mysql_error());
$atendentedb = array();
//put selected people in array
while ($row = mysql_fetch_assoc($atendentes)) {
$atendentedb[] = array('nome' => $row["nome"], 'online' => false);
}
//take people online now and check in selected people
$names = modWhosonlineCustom::getOnlineUserNames();
foreach ($names as $name):
//foreach ($atendentedb as $atendente):
for($i = 0; $i < count($atendentedb); $i++):
$att = strtolower($name->username);
if ($atendentedb[$i]['nome'] == $att):
$atendentedb[$i]['online'] = true;
break;
endif;
endfor;
endforeach;
//check each selected people
foreach ($atendentedb as $atendente) :
//save temporary data
$online_ = $atendente['online'];
$nome_ = $atendente['nome'];
//if selected people online
if ($online_) :
//take status to show
$status = mysql_query("SELECT status FROM atendentes WHERE nome = '$nome_' LIMIT 1") or die(mysql_error());
while ($row = mysql_fetch_assoc($status)):
$statusdb = $row["status"];
endwhile;
//verify and save deppending on status
switch ($statusdb):
//if online
case "disponivel":
$descricao = mysql_query("SELECT hp_online FROM atendentes WHERE nome = '$nome_' LIMIT 1") or die(mysql_error());
while ($row = mysql_fetch_assoc($descricao)):
$online[] = array('info'=>$row['hp_online']);
endwhile;
break;
//if busy
case "ocupado":
$descricao = mysql_query("SELECT hp_busy FROM atendentes WHERE nome = '$nome_' LIMIT 1") or die(mysql_error());
while ($row = mysql_fetch_assoc($descricao)):
$ocupado[] = array('info'=>$row['hp_busy']);
endwhile;
break;
endswitch;
//if offline
else:
$descricao = mysql_query("SELECT hp_offline, horario FROM atendentes WHERE nome = '$nome_' LIMIT 1") or die(mysql_error());
while ($row = mysql_fetch_assoc($descricao)):
$offline[] = array('info'=>$row['hp_offline'], 'horario'=>$row['horario']);
endwhile;
endif;
endforeach;
EDITED
So after following help instructions from DaveRandom I got to this code, which is really a drop away from the right format, except for the "mysterious" behaviour with results coming from array $offline, that are displaying all in "block" (all cells in a row, or all cells in a column) while the other arrays are displaying perfectly(??).
//group people
$online = $ocupado = $offline = array();
//select people to group
$query = "SELECT nome, status, hp_online, hp_busy, hp_offline, horario
FROM atendentes
ORDER BY nome";
$atendentes = mysql_query($query) or die(mysql_error());
$atendentedb = array();
// put selected people in array
while ($row = mysql_fetch_assoc($atendentes)) {
$atendentedb[strtolower($row['nome'])] = array_merge($row, array('online' => FALSE));
}
//take people online now and check in selected people
$names = modWhosonlineCustom::getOnlineUserNames();
foreach ($names as $name) {
$uname = strtolower($name->username);
if (isset($atendentedb[$uname])) $atendentedb[$uname]['online'] = TRUE;
}
//check each selected people
foreach ($atendentedb as $name => $atendente) {
//if selected people online
if ($atendente['online']) {
//verify and save deppending on status
switch ($atendente['status']) {
//if online
case 'disponivel':
$atendentedb[$name]['info'] = $online[] = $atendente['hp_online'];
break;
//if busy
case 'ocupado':
$atendentedb[$name]['info'] = $ocupado[] = $atendente['hp_busy'];
break;
}
//if offline
} else {
$atendentedb[$name]['info'] = $offline[] = $atendente['hp_offline'];
$atendentedb[$name]['info'] = $offline[] = $atendente['horario'];
}
}
//*******Display Results
$conteudo = array_merge($online, $ocupado, $offline);
$max_colunas = 2; // numero de colunas
// Start the table
echo '<table width="100%" cellpadding="5" border="1">'."\n";
// Loop all the objects
for ($i = 0, $j = 0; isset($conteudo[$i]); $i++) {
if ($j == 0) {
// Output the beginning of a row
echo " <tr>\n";
}
// Always output a data cell
echo " <td>$conteudo[$i]</td>\n";
if (++$j >= $max_colunas) {
// Output the end of a row and reset the cell counter
echo " </tr>\n";
$j = 0;
}
}
if ($j) {
// We may end up with an incomplete row at the end, so pad it with empty cells
// and close the row
while ($j++ < $max_colunas) {
echo " <td></td>\n";
}
echo " </tr>\n";
}
// Close the table
echo "</table>";
I would say that the first thing to do here is to "flatten" the array - having the multiple dimensions makes this a lot more complicated than it needs to be. So rather than creating $conteudo like this:
$conteudo = array($online, $ocupado, $offline);
...do this instead:
$conteudo = array_merge($online, $ocupado, $offline);
Then you can do this:
$max_colunas = 2; // numero de colunas
// Start the table
echo '<table width="100%" cellpadding="5" border="1">'."\n";
// Loop all the objects
for ($i = 0, $j = 0; isset($conteudo[$i]); $i++) {
if ($j == 0) {
// Output the beginning of a row
echo " <tr>\n";
}
// Always output a data cell
echo " <td>$conteudo[$i]</td>\n";
if (++$j >= $max_colunas) {
// Output the end of a row and reset the cell counter
echo " </tr>\n";
$j = 0;
}
}
if ($j) {
// We may end up with an incomplete row at the end, so pad it with empty cells
// and close the row
while ($j++ < $max_colunas) {
echo " <td></td>\n";
}
echo " </tr>\n";
}
// Close the table
echo "</table>";
See it working
EDIT
Try this code for generating your arrays. Note that the structure of your output arrays has been altered to fit my code sample above - if you use this data anywhere else in you script, you will need to modify that code as well. I have modified this so that there is only one database query, which would seem to be all that is required. I have also modified it so that the $atendentedb holds all the user data, including the status and info keys, and all rows contain a horario key.
Because of the fact that your input arrays originally contained more data than the ones created by this code will, the code may need further modification - but try this out and see how you get on.
//group people
$online = $ocupado = $offline = array();
//select people to group
$query = "SELECT nome, status, hp_online, hp_busy, hp_offline, horario
FROM atendentes
ORDER BY nome";
$atendentes = mysql_query($query) or die(mysql_error());
$atendentedb = array();
// put selected people in array
while ($row = mysql_fetch_assoc($atendentes)) {
$atendentedb[strtolower($row['nome'])] = array_merge($row, array('online' => FALSE));
}
//take people online now and check in selected people
$names = modWhosonlineCustom::getOnlineUserNames();
foreach ($names as $name) {
$uname = strtolower($name->username);
if (isset($atendentedb[$uname])) $atendentedb[$uname]['online'] = TRUE;
}
//check each selected people
foreach ($atendentedb as $name => $atendente) {
//if selected people online
if ($atendente['online']) {
//verify and save deppending on status
switch ($atendente['status']) {
//if online
case 'disponivel':
$atendentedb[$name]['info'] = $online[] = $atendente['hp_online'];
break;
//if busy
case 'ocupado':
$atendentedb[$name]['info'] = $ocupado[] = $atendente['hp_busy'];
break;
}
//if offline
} else {
$atendentedb[$name]['info'] = $offline[] = $atendente['hp_offline'].' '.$atendente['horario'];
}
}
I think you should update counter inside
foreach ($col as $cell) { } so it will count elements of the inner arrays and also move decalration of <tr> there.
if (!is_int($i/2)) { print '<tr><td>' }
