I have a little question for you!
I make a selection from mysql my buttons for example:
$query = mysql_query("select * from navigation");
while ($row = mysql_fetch_assoc($query)) {
echo '$row['name']';
}
so I call all the navigation from mysql and I have a class in css which is called as .active, this class make a active button when I click it, but how can I make the first button active?
$query = mysql_query("select * from navigation");
while ($row = mysql_fetch_assoc($query)) {
if ($row['id'] == $_GET['id'])) {
echo '<a class="active" href="?id=$row['id']">$row['name']</a>';
} else {
echo '$row['name']';
}
}
Try this.
<?PHP
$query = mysql_query("select * from navigation");
$first = true;
while($row = mysql_fetch_assoc($query)) {
if ((!array_key_exists('id', $_GET) && $first) || $row['id'] == $_GET['id']) {
$extra = 'class="active"';
$first = false;
} else
$extra = '';
echo "<a $extra href=\"?id={$row['id']}\">{$row['name']}</a>";
}
?>

I have separate question really which I need help. I only want to display say 20 characters from 'content'.
<?php
$output = '';
if(isset($_GET['q']) && $_GET['q'] !== ' ') {
$searchq = $_GET['q'];
$q = mysqli_query($db, "SELECT * FROM article WHERE title LIKE '%$searchq%' OR content LIKE '%$searchq%'") or die(mysqli_error());
$c = mysqli_num_rows($q);
if($c == 0) {
$output = 'No search results for <strong>"' . $searchq . '"</strong>';
} else {
while($row = mysqli_fetch_array($q)) {
$id = $row['id'];
$title = $row ['title'];
$content = $row ['content'];
$output .= '<a href="article.php?id=' .$id. '">
<h3>'.$title.'</h3></a>'.$content.'';
}
}
} else {
header("location: ./");
}
print("$output");
mysqli_close($db);
?>
i will answer your first question:
insert this line after:
$content = $row ['content'];
if(strlen($content)>20) $content=substr ($content,0,19);
I am a completely newbie in programming php I would like to make this code below return many arrays(to flash as3), however I only receive one array.Can anyone please pinpoint what is my mistake here? thanks.
$data_array = "";
$i = 0;
//if(isset($_POST['myrequest']) && $_POST['myrequest'] == "get_characters")
//{
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql))
{
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1)
{
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
else
{
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
echo "returnStr=$data_array";
exit();
}
When you write your exit insight your loop you stop executing your program and you get only one record. You should set the echo and exit after your while loop.
$data_array = "";
$i = 0;
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql)) {
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1) {
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
} else {
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
}
echo "returnStr=$data_array";
exit();
Those two last line of your should be outside of your loop:
$data_array = "";
$i = 0;
//if(isset($_POST['myrequest']) && $_POST['myrequest'] == "get_characters")
//{
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql))
{
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1)
{
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
else
{
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
}
echo "returnStr=$data_array";
exit();
If you would name the columns that you want in the SELECT then it's much simpler. Make sure to use MYSQLI_ASSOC in the fetch:
$sql = mysqli_query($conn, "SELECT Username, Fb_id, Access_token, Fb_sig, Char_id FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql, MYSQLI_ASSOC))
{
$data_array[] = implode('|', $row);
}
echo "returnStr=" . implode('(||)', $data_array);
exit();
I am modifying a site built in PHP with content drawn from a SQL database. The original developer had the navigation created with the following code. It creates the navigation from the CMS pages - it works fine for top level pages but I am trying to modify the way subpages are presented.
What I want it to do is when a subpage is present, it first opens a DIV containing formatting, then populates the subpagemenu by using the 'while' statement below. Finally, when the subpagemenu is finished, it closes the DIV.
I can't seem to work out which condition 'opens' the subpage menu before it goes through the loop of filling out the subpage menu.
Any and all help appreciated - thanks!

added the tag where it is requrired
the code i have below basically behaves as a friend search engine where you can add someone if you don't have them on you account. So i am trying to do the following: If exists it should just display the friend and if not then it should say add friend.
I got it to work but the tail end of the query (please see this comment "//Problem code - when i use this echo below this where it repeats 3 times") is giving me trouble where it repeats Add 3 times.
<?php
$num_rows1 = mysql_num_rows($result);
if ($result == "") {
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if ($rows == 0) {
print("<div id=norequests>No results for <strong>$q
</strong></div>");
}
elseif ($rows > 0) {
while ($row = mysql_fetch_array($query))
{
$person = htmlspecialchars($row['full_name']);
$linksys = htmlspecialchars($row['name']);
$pid = htmlspecialchars($row['system_id']);
}
print("");
}
}
else{
echo '<div id="error">No results.</div>';
}
$sql = "SELECT `Friend_id` from `friends_container`
WHERE `System_id` = '$sid'";
$result = mysql_query($sql);
$query = mysql_query($sql) or die("Error: " . mysql_error());
if ($result == "") {
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if ($rows == 0) {
print("");
}
elseif ($rows > 0)
{
while ($row = mysql_fetch_array($query))
{
$existing = htmlspecialchars($row['Friend_id']);
if ($existing == $pid) {
echo("<img src=$linksys />$person - Already Existing");
}
else
//Problem code - when i use this echo below this where it repeats 3 times
{
echo("Add $person");
}
}
?>
You must have 3 images stored for each account.
Your query will always result in a multiple result. what you should do is use php to convert it to something which will result in a better option or say convert the result in an array for convenience.
1) I want to save case 1 value to an array. Return this array and pass it to a function. The code become case 2, but no result come out, where is the problem?
2) In function display_urls, i want to echo both $url and $category. What should i do in IF condition or add another line of code?
function display_urls($url_array)
{
echo "";
if (is_array($url_array) && count($url_array)>0)
{
foreach ($url_array as $url)
{
echo "".$url."";
echo "".$category."";
}
}
echo "";
}
case 1: work fine
$result = oci_parse($conn, "select * from bookmark where username ='$username'");
if (!$result){ $err = oci_error(); exit; }
$r = oci_execute($result);
$i=0;
echo "";
while( $row = oci_fetch_array($result) ){
$i++;
echo "";
echo "".$row['USERNAME']."";
echo "".$row['BM_URL']."";
echo "".$row['CATEGORY']."";
echo "";
}
echo "";
case 2:
$url_array = array();
while( $row2 = oci_fetch_array($result, OCI_BOTH)){
$i++;
$url_array[$count] = $row[0];
}
return $url_array;
I think you probably want something like this:
function display_urls($url_array)
{
echo "";
if (is_array($url_array) && count($url_array)>0)
{
foreach ($url_array as $url)
{
echo "".$url['BM_URL']."";
echo "".$url['CATEGORY']."";
}
}
echo "";
}
$result = oci_parse($conn, "select * from bookmark where username ='$username'");
if (!$result){ $err = oci_error(); exit; }
$r = oci_execute($result);
$url_array = array();
while( $row = oci_fetch_array($result, OCI_ASSOC)){
$url_array[] = $row;
}
display_urls($url_array);
This will store all the information on the URLs in $url_array with a lookup by column name.
