Outputting Array Elements	View Content

I have converted xml into an array with no problems, however I'm having difficulty outputting the various attributes.

Here is a sample:

Code: [Select]
[0] => Array
(
[@attributes] => Array
(
[YourId] => 1082-1
[Name] => Woodwards Metals
[Description] =>
)

)
The bit that is confusing me is the @attributes part. How would I output the 'Name' element for example?

While Loop Not Outputting Array As Expected

I am trying to load all rows from a table in a database into a table on a webpage. I cannot understand why the following code does not work:
Code: [Select]
<?php ...
echo "You are currently in a fleet. The details of the fleet are below.<br>";
$fleetName = $_SESSION['charFleetName'];
$sqlFleetDetails = "SELECT * FROM `$fleetName`";
$queryFleetDetails = mysql_query($sqlFleetDetails);
echo "<table>";
echo "<tr>";
echo "<th>Pilot</th>";
echo "<th>Ship</th>";
echo "<th>Type</th>";
echo "</tr>";
while($rowFleetDetails = mysql_fetch_array($queryFleetDetails)) {
$charId = $rowFleetDetails['charId'];
$charName = $rowFleetDetails['charName'];
$shipHull = $rowFleetDetails['shipHull'];
$shipType = $rowFleetDetails['shipType'];
echo "<tr>";
echo "<td><a href=\"#\" onClick=\"CCPEVE.showInfo{1377, " . $charId . "}>" . $charName . "</a></td>";
echo "<td>" . $shipHull . "</td>";
if($shipType == 1)
echo "<td>Logistics</td>";
if($shipType == 2)
echo "<td>DPS Boat</td>";
if($shipType == 3)
echo "<td>Sniper 120Km+</td>";
if($shipType == 4)
echo "<td>Off-grid Booster</td>";
echo "</tr>";
}
echo "</table><br>";
I originally had the $rowFleetDetails['charId'] and others in the echo instead of loading them into variables then echoing the variables but changed it to see if that was working, neither is. If I add an extra line outside of the while loop to echo the output of the array then the information is displayed fine, so I know that the information is being transferred from the table into the array correctly, but why is it not outputting properly in the While loop?

Outputting An Array Into A Textarea Field

Hello, this is my first post here. I am trying to output the rows of a certain query in sequence after a POST has been requested. I have been successful in getting the output in a pure php file but when I try to implement this in a web page with html/css, I can't echo the array in arbitrary locations after the post has processed. This is the code which outputs successfully in a pure php file, but I need it to work in a <textarea> field as the results of a search

$rows2 = array();
$rows3 = array();
while($stmt->fetch()){
$rows2[] = $stratoparse;
$rows3[] = $date;
}
 $search = array();
for($i=0;$i<=$num_rows;$i++){
echo $rows3[$i].'&nbsp;'.$rows2[$i].'<br>'.'<br>';
}
}

To further iterate what I am asking. When errors are stored, you write something like

$errors['username']="A username is required.";

Then in any location of a webpage I can call this or show it, provided by this

<?php isset($errors['username']) ? $errors['username']:" ");?>

That is the same thing I am trying to do with this array which can be an arbitrary count of rows... I have not been successful in getting this to work... I have been told of string concatenation... I don't know what to do Thank you for any help

Problem Outputting Multi-dimensional Array

Similar Tutorials

I have a Q&A Form/script where registered Users can share there thoughts on 10 Questions.

On the backend I have these tables: member, answer, question

Thanks to some help last night, I have been able to do a LEFT join and store the above data in a multi-dimensional array which always stoes the 10 Questions, and also any Answers that the User may have responded to. (Questions are optional.)

I am having a hell of a time DISPLAYING this multi-dimensional array.

The key is that I want my PHP and array to stay at the top of my script and use minimal PHP in my HTML section.

Here is how I query the data and build my array...

// ********************
// Build Q&A Query. *
// ********************

// Build query.
$q7 = "SELECT q.id, q.question_no, q.question_text, a.answer_text
FROM bio_question AS q
LEFT JOIN bio_answer AS a
ON q.id=a.question_id
AND a.member_id =?
ORDER BY q.question_no";

// Prepare statement.
$stmt7 = mysqli_prepare($dbc, $q7);

// Bind variables to query.
mysqli_stmt_bind_param($stmt7, 'i', $memberID);

// Execute query.
mysqli_stmt_execute($stmt7);

// Store results.
mysqli_stmt_store_result($stmt7);

// Check # of Records Returned.
if (mysqli_stmt_num_rows($stmt7) > 0){
// Questions Found.

// Bind result-set to variable.
mysqli_stmt_bind_result($stmt7, $questionID, $questionNo, $questionText, $answerText);

// Populate PHP array with Questions & Answers.
$x=1;
while (mysqli_stmt_fetch($stmt7)){
$thoughtsArray[$x] = array('questionID' => $questionID,
'questionText' => $questionText,
'answerText' => $answerText);
$x=$x+1;
}

echo '<pre>';
print_r($thoughtsArray);
echo '</pre>';

// Close prepared statement.
mysqli_stmt_close($stmt7);

And in my HTML Form, here is how I am attempting to dynamically build the Q&A section...

<form id="changeAnswers" action="" method="post">
<fieldset>
<legend>Change Profile Answers</legend>

<?php
echo '<p>TEST: ' . $thoughtsArray[4]['answerText'] . '</p>';

foreach($thoughtsArray as $questionNo => $qaArray) {
echo '<label for="question' . $questionNo . '">' . $questionNo . '.) ' . $qaArray['questionText'] . '</label>';
echo '<textarea id="question' . $questionNo . '" name="thoughtsArray[' . $questionNo . '][\'answerText\']" cols="60" rows="2">' .
(isset($questionNo]) ? "htmlentities($thoughtsArray[$questionNo]['answerText'], ENT_QUOTES" : '') .
'</textarea>';
}
?>

I am able to retrieve and display the Questions from my multi-dimensional array as seen above, however, for the life of me, I cannot get the Input Fields (with any Answers) to work properly. I either get compile errors, or the code runs but my Input Fields are blank even when an Answer should be displayed?!

I am hoping this is just a syntax and/or reference error. I'm still new to arrays, so properly retrieving an Answer from a multi-dimensional array is really tricky for me!!

So close and yet so far away?!

Can someone please help me out??

Thanks,

Debbie

Creating Multidimension Array From Mysql Source And Outputting

Similar Tutorials

View Content

I have whiled my way through any number of forums and help pages so far. However, since I am not quite comfortable yet with PHP, I am not sure which option I have been given would be the right one.

What I am trying to do: Create the source for a set of drop-down menus. The dropdown menu has columns, and then a H2 and P that go in each column, in varied numbers, so you have
column1, h2 p; h2 p; h2 p
column2, h2 p; h2 p
etc....make sense? I am using an MySQL table as source so I can have a little CMS dashboard where I can change these and other values on the fly.

So I have a MySQL table where I have a field that identifies the column (page name), and then values to fill the h2 and p tags. I.E.:
page_name, content_title, content_text

The idea, therefore, is to use PHP to figure out what the column names (that are repeated) in the mysql table and then create the dropdown based on the value in the subsidiary fields. Output is as a string in a variable value that is output via return ();

My best estimation of how to do this is to use php to create a multidimensional array from the query result, where the first column is the page_name, followed by an array, the array being the remainder of the information.

Based on information scrounged from other sources, I have come up with this so far:

$query = "SELECT * FROM tbl_mainmenu WHERE mainmenu_type = '$mmtype'"; // what the query is
$result = mysql_query ($query, $dbc); // connect to database and run query, setting the the result to dummy array variable '$result'

// establish the multidimensional array

$mmcontent_array = array ();

//create the array where the values are content page and associated values in an array per each content page

while ($result = mysql_fetch_assoc ())

{

$page_name = $result['content_page'];

$mmcontent_array['content_page'] = $result;

}

foreach ($mmContent_array[] as $key=>$value)

{

foreach ()

{

$tmpelements[] = '<div class="col_2"><h2>' . $element[content_title] . "</h2>\n<p>" . $element[content_text] . "</p>\n</div>";

$elements = implode("\n",$tmpelements) . "\n"

}

$tmp[] = '<li><a href="#" class="drop">Products</a>\n<div class="dropdown_2columns">' . $elements . 'whatever tags will close this')

}

Am I even in the ballpark?

I am not sure which way to nest the foreach ()'s. The example I was working from used echo ()'s, and I am not sure if using $variable = implode () makes the task different.

As a start, I am just wondering if I am creating the multidimensional array correctly?

Modifying Elements In An Array

Hi Guys,

I have an array that contains a few records from mysql.

The array looks like so
Array
(
    [0] => Array
        (
            [id] => 1
            [name] => New Product
            [url] => New-Product
            [title] => Title Used On Heading
            [description] => Write a 3 to 5 Paragraph summary of product
            [preview_image] => 0
            [body_image] => 0
            [status] => 1
        )

    [1] => Array
        (
            [id] => 2
            [name] => New Product
            [url] => New-Product
            [title] => Title Used On Heading
            [description] => Write a 3 to 5 Paragraph summary of product
            [preview_image] => 0
            [body_image] => 0
            [status] => 0
        )
)

I am trying to modify the preview_image value on each of the arrays in this array like so;

//modify the products array
foreach($data['raw_products'] as $data['products'])
{
//set the preview image row
$data['products']['preview_image'] = anchor('admin/list_products/#', "View IMG", array("onHover" => "admin.previewIMG('".$data['products']['preview_image']."')", "class" => "noLink"));
//set the body image row
$data['products']['body_image'] = anchor('admin/list_products/#', "View IMG", array("onHover" => "admin.bodyIMG('".$data['products']['body_image']."')", "class" => "noLink"));

}

It works fine for one record, but then when I print_r($data['products']) I only see one record. Any help would be greatly appreciated.

I used DOM to parse data from html, then I made the data go into an array. the array now looks like Array([0]->street[1]->city, st, zip[2]->phone[3]->fax) and it is quite a long array.

Printing Elements Of An Array

Hi,

I'm a PHP novice and trying to print out elements of what appears to be a multi-dimensional array, but I can't figure it out. I'm able to use print_r() to dump the array.

This output was produced using print_r($array);

I'm trying to access our contacts using the vendor's PHP API, but I'm not much of a PHP programmer. The array is stored in $contacts, using the vendor's getList() function. I believe I'm able to download the whole list of contacts in an array, but I can't iterate through it. I'd like to print out the elements of the array in CSV format.

This looks like some complicated multidimensional array.

I also have no idea what the array keys are ('isPublished', etc).

$contacts = $contactApi->getList($searchFilter, $start, $limit, $orderBy, $orderByDir, $publishedOnly, $minimal);
foreach ($contacts as $var) {
echo "\n", $var['isPublished'], "\t\t", $var['value'];
}

I've also tried something like this:

foreach ($contacts as $contact) {
echo "\n", $contacts[$contact['isPublished']];
}

Other ideas greatly appreciated.

Hello,

I have two arrays:
$questions, which has 'question_id' as one of its keys and
$assignment_questions which is a subset of $questions, pulled off my database.

Using php, I'd like to construct a 3rd array which takes my $questions array and removes from it any question that has a question_id which can be found in both $questions and $assignment_questions, in addition to the other values associated with a particular question_id.

For example, $questions has: question_id, solution, author (and other keys). Is there any way to check if a particular key matches and then zap out all of the corresponding fields (solution, author, etc.)?

Adding Elements From One Multidimensional Array To Another

Suppose I have 2 arrays like the two below. I want to change each element of the first array. I want to add [‘person_id’] => 3 to each element and I want to add the [name] element from each element of the second array to each element of the first, with the [name] value corresponding. i.e. [name] from the first element in array 2 added to the first element of array one, [name] from the second element of array two added to the second element of array one, and[name] from the third element of array two added to the third element of array one. The element can be called "name" in each element of the first array.

Thus the person_id would be the same in all elements of array one and the name element from array two would be added, changing for each element.

It’s kind of a foreach in a foreach and I couldn’t figure out how to do it. array_walk might be useful as well though I couldn’t figure that our either.

What’s happening here is that I am uploading three image files and want to insert the information about each file into corresponding file fields in a row determined by the person_id, extracting the image filenames from array 2.

Thanks for help with this,

I have it to where it groups two parts of the Array randomly but I need to make it where it won't pair the same together, or if it has already been paired with a team then use another team. Each value of the array can only be used once.

Here is my code
shuffle($teamname);

$loopCount = $games;

for ($i = 0; $i < $loopCount; $i++) {
    $player1 = array_pop($teamname);
    $player2 = array_pop($teamname);
if(is_null($player1))
{
echo 'Not enough different teams to create '.$games.' games';
break;
}
    // output to screen
    echo "Team: " . $player1 . " Vs Team: " . $player2 . "<br />";

}
}
