I made this code write data into an HTML table:
<?php
//DB Verbindung
$con = mysqli_connect("localhost","root","","altislife");
$header = -1;
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="SELECT * FROM players";
if ($result=mysqli_query($con,$sql))
{
echo "<thead><tr>";
while ($fieldinfo=mysqli_fetch_field($result))
{
echo "<th>$fieldinfo->name</th>";
$header++;
echo "$header";
}
echo "</tr></thead>";
mysqli_free_result($result);
}
if ($result=mysqli_query($con,$sql))
{
echo "<tbody>";
for ($i=0; $i < $header; $i++) {
while($sql = mysqli_fetch_array($result))
{
echo "<tr><td>" . $sql[$i] . "</td><td> ";
}
}
echo "</tbody>";
}
mysqli_close($con);
The problem is that it only fills the first column.
Then I tried this:
<?php
//DB Verbindung
$con = mysqli_connect("localhost","root","","altislife");
$header = -1;
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="SELECT * FROM players";
if ($result=mysqli_query($con,$sql))
{
echo "<thead><tr>";
while ($fieldinfo=mysqli_fetch_field($result))
{
echo "<th>$fieldinfo->name</th>";
$header++;
echo "$header";
}
echo "</tr></thead>";
mysqli_free_result($result);
}
if ($result=mysqli_query($con,$sql))
{
echo "<tbody>";
while($sql = mysqli_fetch_array($result))
{
for ($i=0; $i < $header; $i++) {
echo "<tr><td>" . $sql[$i] . "</td><td> ";
}
}
echo "</tbody>";
}
mysqli_close($con);
The problem with this code is the same as with the first example. Can anyone see my mistake?
if ($result=mysqli_query($con,$sql))
{
$row = mysqli_fetch_assoc($result);
$html = '<table><tr><th>'.implode('</th><th>',array_keys($row)).'</th></tr>';
do {
$html .= '<tr><td>'.implode('</td><td>',$row).'</td></tr>';
}while($row = mysqli_fetch_assoc($result));
$html .='</table>';
}
echo $html;
Try it this way, and figure out how this works ;-)
Points to your code:
tbody
is not table
yours frist example has no table tags <tr></tr>
your second example misses a close tag thead
and tbody
are optional and have no impact on the html Last point: it is unnesessary to run the sql twice to generate a table
implode($sep,$arr)
implode takes too args and seperator like <th></th>
and merges all entries of an array with is like: array('a','b','c')
becomes a<th></th>b<th></th>c
mysqli_fetch_assoc
vs mysqli_fetch_array
second gives something like [0=>'a',1=>'b']
and the first ['name'=>'a','color'=>'b']
You need to fetch the entire record in your db, not just one field. Try fetch_assoc (see http://www.w3schools.com/php/php_mysql_select.asp ).
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
}
} else {
echo "0 results";
