Waiting for UPDATE to finish before refreshing page - php

Question

I have an HTML form that update a table in MySQL. Unfortunatly, my page reload with the pre-updated data from MySQL. Is there a way to tell mysqli in PHP to wait for UPDATE to complete before reloading (and doing the SELECT again) the page?
Thanks!
(edit: adding portion of code)
$mysql = mysqli_connect($host,$username,$password,$dbname);
$series_mysql = $mysql->query("SELECT Name, Path, Language FROM subtitles_config");
$series_list = array();
while($serie = mysqli_fetch_array($series_mysql))
{
array_push($series_list,array($serie["Name"],$serie["Path"],$serie["Language"]));
}
sort($series_list);
if ($series_list != Null)
{
echo "<form action='?' method='post'><table><tr><th>Nom</th><th>Sous-titres</th></tr>\n\r";
foreach ($series_list as $serie)
{
echo "<tr><td><input type=text size=40 readonly name='row[]' value='" . htmlspecialchars($serie[0], ENT_QUOTES) . "'><input type='hidden' name='row[]' value='" . htmlspecialchars($serie[1], ENT_QUOTES) . "'</td><td>";?>
<select name='row[]'>
<option value="aucun"<?php if ($serie[2] == "aucun"): ?> selected="selected"<?php endif; ?>>aucun</option>
<option value="fr"<?php if ($serie[2] == "fr"): ?> selected="selected"<?php endif; ?>>fr</option>
<option value="en"<?php if ($serie[2] == "en"): ?> selected="selected"<?php endif; ?>>en</option>
<option value="fr,en"<?php if ($serie[2] == "fr,en"): ?> selected="selected"<?php endif; ?>>fr,en</option>
</select><?php
echo "</td></tr>\n\r";
}
echo "</table><input type='submit' name='update' value='Mettre à jour' /></form>\n\r";
}
if ( isset( $_POST['update']))
{
foreach (array_chunk($_POST['row'],3) as $serie)
{
$mysql->query("UPDATE subtitles_config SET Language='" . $serie[2] . "' WHERE Path='" . addslashes($serie[1]) . "'");
}
}

<?php
$mysql = mysqli_connect($host,$username,$password,$dbname);
if ( isset( $_POST['update'])) {
foreach (array_chunk($_POST['row'],3) as $serie) {
$mysql->query("UPDATE subtitles_config SET Language='" . $serie[2] . "' WHERE Path='" . addslashes($serie[1]) . "'");
}
}
$series_mysql = $mysql->query("SELECT Name, Path, Language FROM subtitles_config");
$series_list = array();
while($serie = mysqli_fetch_array($series_mysql)) {
array_push($series_list,array($serie["Name"],$serie["Path"],$serie["Language"]));
}
sort($series_list);
if ($series_list != Null) {
echo "<form action='?' method='post'><table><tr><th>Nom</th><th>Sous-titres</th></tr>\n\r";
foreach ($series_list as $serie) {
echo "<tr><td><input type=text size=40 readonly name='row[]' value='" . htmlspecialchars($serie[0], ENT_QUOTES) . "'><input type='hidden' name='row[]' value='" . htmlspecialchars($serie[1], ENT_QUOTES) . "'</td><td>";
?>
<select name='row[]'>
<option value="aucun"<?php if ($serie[2] == "aucun"): ?> selected="selected"<?php endif; ?>>aucun</option>
<option value="fr"<?php if ($serie[2] == "fr"): ?> selected="selected"<?php endif; ?>>fr</option>
<option value="en"<?php if ($serie[2] == "en"): ?> selected="selected"<?php endif; ?>>en</option>
<option value="fr,en"<?php if ($serie[2] == "fr,en"): ?> selected="selected"<?php endif; ?>>fr,en</option>
</select>
<?php
echo "</td></tr>\n\r";
}
echo "</table><input type='submit' name='update' value='Mettre à jour' /></form>\n\r";
}
Try that.
Your issue was that you were updating everything AFTER you pulled the data for the fields.
