I'm stuck and can't figure this out.
I have this piece of code which is basically generating a table taking data from SQL cursor.
I need to add one extra table row <tr> (which will be filled with additional info) after each row. I've tried putting the new row in several places, but there is never any output data for it. This is someone else's code that I'm trying to modify.
$top_i=min($pagesize-1,$numrows-$start);
for($i = 0;$i<=$top_i;$i++) {
if (($i%2)==1)
echo "<tr class='saraksts_row0'>";
else
echo "<tr class='saraksts_row1'>";
$res=mssql_query("fetch absolute ".($start+$i)." from saraksts_cursor ");
$row=mssql_fetch_array($res);
$itemp = 0;
foreach($fields as $field) {
$key = $field[0];
if($field[2]) {
eval($field[2] );
}
$itemp++;
$val = ($row[$key] == "") ? " " : $row[$key];
// Get rid of right and left border, set topmost border
$st="";
if ($itemp==1)
$st.="border-left-style:none;";
if ($itemp==$numfields)
$st.="border-right-style:none;";
if ($i==$top_i)
$st.="border-bottom-style:solid;";
echo "<td style='$st'>$val</td>";
}
$itemp = 0;
echo "</tr>\n";
}
The place where you want to add the extra row is after closing the first row and before the iteration moves to the next one. Note, it appears that you are doing some styling based on whether the row is odd or even. If you want this new row to have the same styling, I suggest you store the class you're applying to the preceding row so that you can also apply it to this row.
echo "</tr>\n";
echo "<tr><td>...</td><td>...</td></tr>\n"; /* Add the new row here */
}
...
$st.="border-bottom-style:solid;";
echo "<td style='$st'>$val</td>";
}
//Here we go
echo '<td style="blah">'.$yourotherinfo.'</td>';
$itemp = 0;
echo "</tr>\n";

This is going to be a newbie question, so bear with me.
I have a database in which I fetch the data, I would like to create a for loop which will loop through the fetched data and will determine what the lowest time is. This is how my loop looks like: (take into consideration I only took the part out that seemed usefull to post, and $row['timePV'] is a time based value such as: 23:00)
$arrayCount = array();
while ($row = mysqli_fetch_assoc($result)) {
echo "<tr>";
echo "<td>";
echo $row['timePV'];
echo "</td>";
echo "</tr>";
array_push($arrayCount,$row['timePV']);
}
echo "</table>";
}
$c = 100000;
for ($i = 0; $i < sizeof($arrayCount); $i++) {
$arrayCount[$i];
if ($arrayCount[$i] < $c) {
$c = $arrayCount[$i];
echo $c;
} else {
//do something else
}
}
So what I want to achieve: Loop through the stored data and take out the lowest value and display that value, but it only displays all the values.
So my question: How can I make the loop in such way that it will take the lowest value and display it to me?
You don't have to do another loop to calculate lowesttime. You can do it in that while loop with checking previous and present timePv like following
//$timeExample=[["timePV"=>"11:30"],["timePV"=>"11:20"],["timePV"=>"13:30"]];//example of data
$lowestTime = null;//Deault defined it null
while ($row = mysqli_fetch_assoc($result)) {
//foreach($timeExample as $row){ //foreach for run example
if($lowestTime){
$lowestTime=min($lowestTime,strtotime($row['timePV']));//If not null we also get min lowerstTime from previous //and current one
}else{
$lowestTime=strtotime($row['timePV']);//It will work for only first iteration since $lowestTime will null in //first iteration
}
echo "<tr>";
echo "<td>";
echo $row['timePV'];
echo "</td>";
echo "</tr>";
}
echo date("h:i",$lowestTime);//11:20 example out
I'm putting together something that's mean to allow for a user to book seats for a cinema showing. The row and seat numbers for every showing are stored in the database. I'm currently extracting them in the following method so that users can click on a seat button to select that seat for their booking:
echo "<form>";
echo "<table>";
while($row = mysqli_fetch_assoc($result)){
$rownum = $row['row'];
$seat = $row['seat'];
echo "<tr><td><button type=\"submit\" name=\"seatsel\" value=\"$rownum$seat\">$rownum$seat</button></td></tr>";
}
echo "</table>";
Right now this just outputs html showing all of the buttons as a single row in the table. I'd like the output to show seating across a single table row for every one of the table rows in the cinema screen. I'm not sure how to do this exactly given that each row is of differing lengths. E.g row A has twelve seats while row C has eight.
What would be the best way of accomplishing this?
You could easily update your code so that you will get a new table row every time the mysql row has another value. One thing to note is that you might want to add (depending on whether you're already sorting your results) the following ORDER BY row,seat.
echo "<form>";
echo "<table>";
echo "<tr>";
while($row = mysqli_fetch_assoc($result)){
if (!isset($oldrownumber)) $oldrownumber = $row['row'];
else if ($oldrownumber != $row['row']) {
echo "</tr><tr>";
$oldrownumber = $row['row'];
}
$rownum = $row['row'];
$seat = $row['seat'];
echo "<td><button type=\"submit\" name=\"seatsel\" value=\"$rownum$seat\">$rownum$seat</button></td>";
}
echo "</tr>";
echo "</table>";
I am creating a table and want it laid out a certain way and have to retrieve the data from the DB. I am trying to get it set up where it has the usernames across the top example...

my code looks like this and I have been messing around with it for hours and cant figure out why I cant get it set up how I want. Any help would be appreciated. Its a while loop.
while ($pickresults= mysql_fetch_assoc($picksquery)) {
//first row
echo '<th> '.$pickresults['username'].' </th> ';
echo ' <td> '.$pickresults['firstgame'].' </td> '; }
First off, you should learn the HTML code for tables. Your code is putting a Table Header (th) next to a normal column item (td). You need to loop through the headers first then next row loop through the column items or build the strings to echo out.
$headers = $col = "";
while($pickresults= mysql_fetch_assoc($picksquery)){
$headers .= "<th> {$pickresults['username']} </th>";
$col .= "<td> {$pickresults['firstgame']} </td>";
}
echo "<table><tr>$headers</tr><tr>$col</tr></table>";
Your structure is creating a TH then a TD and then a TH and then a TD etc.
This isn't how you create a table, you first need to make the four TH's and THEN you can make the four TD's.
Edit: Marko D has supplied the code to explain what I mean.
First collect table header and body, and then output them. The way you were doing, html was like this, I guess it's easy to see what is wrong with html
<th>name</th>
<td>value></td>
<th>another name</th>
<td>another value</td>
What you need is this:
$td = '';
$th = '';
while ($pickresults= mysql_fetch_assoc($picksquery)) {
$th .= '<th> '.$pickresults['username'].' </th> ';
$td .= '<td> '.$pickresults['firstgame'].' </td> ';
}
echo '<table><tr>' . $th . '</tr><tr>' . $td . '</tr>' . '</table>';
You need to write all usernames in <th>-tags.
I'd put it in an array first, and from the array into the table...
while ($pickresults= mysql_fetch_assoc($picksquery)) {
$picked[]=$pickresults;
}
echo "<table><tr>"; // create table and 1st row
foreach ($picked as $pick) {
echo "<th>{$pick['username']}</th>"; // create 1st line headers
}
echo "</tr><tr>"; // close 1st row and open 2nd
foreach ($picked as $pick) {
echo "<td>{$pick['firstgame']}</td>"; // create 2nd line...
}
echo "</tr></table>"; // close 2nd row and table
The array $carry_over returns a really long list of entries, too long for my printout page. I would love to make it in such a way that after 4 entries, it breaks and goes to the next line and breaks at the next four entries until all entries are in.
How can i do this?
Thanks
echo "<table class=\"altrowstable\" bgcolor = gold >\n";
$count = 0;
echo "<tr align= \"center\">\n";
$carry_over = array();
$score_count = mysql_numrows($query8);
echo "<td>"."Failed: ";
if($score_count !== 0){
while ($row8 = mysql_fetch_assoc($query8)) {
echo "<th>".$row8['course_code']."</th>";
if ( $count == 7 ){
echo "</tr>\n";
echo "</table>";
}
}
}
Update : Now only the first 7 entries are covered inside the table tags, the subsequent ones are outside the table tags. How can i put them in the tabke tags?
Thanks
Not sure if this is what you are looking for, but you could try:
$count = 0;
echo "<tr>";
while ($row8 = mysql_fetch_assoc($query8)) {
echo "<th>" . $row8['course_code'] . "</th>";
$count++;
if(count == 4) {
echo "</tr><tr>";
$count = 0;
}
}
echo "</tr>";
It looks like you're using a table for list data. Instead of using a <table>, you should be using a <ul> with <li> for each element. This can then be styled so that each li has display: inline-block;, for example.
I cannot tell what the table looks like from the code above, but you can put an iterator in to count to four then wrap. You also may want to check out Wordwrap
The code below works great. It prints out items in a MySQL database as an HTML table. However, the database has entries where the first column (the variable "site") is blank. How can I have this table exclude rows / entries where "site" is blank?
$result=mysql_query("SHOW TABLES FROM database LIKE '$find'")
or die(mysql_error());
if(mysql_num_rows($result)>0){
while($table=mysql_fetch_row($result)){
print "<p class=\"topic\">$table[0]</p>\n";
$r=mysql_query("SELECT * , itemsa - itemsb AS itemstotal FROM `$table[0]` ORDER BY itemstotal DESC");
print "<table class=\"navbar\">\n";
while($row=mysql_fetch_array($r)){
$itemstotal = $row['itemsa'] - $row['itemsb'];
print "<tr>";
print "<td class='sitename'>".'<a type="amzn" category="books" class="links2">'.$row['site'].'</a>'."</td>";
print "<td class='class1'>".'<span class="class1_count" id="class1_count'.$row['id'].'">'.number_format($itemstotal).'</span>'."</td>";
print "<td class='selector'>".'<span class="button" id="button'.$row['id'].'">'.''.Select.''.'</span>'."</td>";
}
print "</tr>\n";
}
print "</table>\n";
}
else{
print "";
}
Add a where clause to the SQL query.
WHERE `site` <> ''
or
WHERE `site` != ''
should work.
However, if you want the rows where site is blank for other PHP options, it would be better to filter out the blank sites in the PHP and not the MySQL query.
Just put the following before the print calls in your while loop:
if (trim($row['site']) == '') {
// skip output of this row if site is empty
continue;
}
while($row=mysql_fetch_array($r)){
if($row['site'] != "") {
$itemstotal = $row['itemsa'] - $row['itemsb'];
print "<tr>";
print "<td class='sitename'>".'<a type="amzn" category="books" class="links2">'.$row['site'].'</a>'."</td>";
print "<td class='class1'>".'<span class="class1_count" id="class1_count'.$row['id'].'">'.number_format($itemstotal).'</span>'."</td>";
print "<td class='selector'>".'<span class="button" id="button'.$row['id'].'">'.''.Select.''.'</span>'."</td>";
}
}
The simplest solution would be to insert the following line into your inner while block:
while($row=mysql_fetch_array($r)){
if (!trim($row['site'])) continue; // skip empty rows
$itemstotal = $row['itemsa'] - $row['itemsb'];
Edit: Actually, it looks like that $itemstotal variable isn't needed; it's being calculated as a "virtual" itemstotal column in the SQL query. If you replace "number_format($itemstotal)" with "number_format($row['itemstotal'])" a few lines down, you can get rid of the "$itemstotal = ..." line entirely.
