currently internship I have to make a website with the establishment of an external API, I can display the data, parcontre I would like the displays in a <select>
However when I make my code nothing is displayed, however if I display it in a data p appears but in a table, how to display the data in a <select>
function dog_func ($atts) {
$contents = file_get_contents('https://dog.ceo/api/breeds/list/all');
$contents_arr = json_decode($contents);
echo "<select>" . $contents ."</select>" ;
}
add_shortcode ('dog_api', 'dog_func');
OR
function dog_func ($atts) {
$contents = file_get_contents('https://dog.ceo/api/breeds/list/all');
$contents_arr = json_decode($contents);
echo '<select multiple value="$contents"></select>';
}
add_shortcode ('dog_api', 'dog_func');
During these tests nothing is displayed
AND
function dog_func ($atts) {
$contents = file_get_contents('https://dog.ceo/api/breeds/list/all');
$contents_arr = json_decode($contents);
echo "<p>" . $contents ."</p>" ;
}
add_shortcode ('dog_api', 'dog_func');
Walk but display in "gross"
You can do this for <select> like this
$contents_arr = json_decode($contents);
echo '<select>';
foreach($contents_arr->message as $key=> $ca){
echo "<option value='".$key."'>" . $key ."</option>" ;
}
echo '</select>';
And for <p>
$contents_arr = json_decode($contents);
foreach($contents_arr->message as $key=> $ca){
echo "<p>" . $key ."</p>" ;
}
It's actually a json object which you can decode it into the array and then parse it through foreach loop

I've created a page that grabs data from a CSV (http://liamjken.com/aim-parse/aim-websites-new.csv) and displays it on this page http://www.liamjken.com/aim-parse/parse.php?17
?17 references the row in the csv file. so if I change that to ?10 it pulls the info from a different row.
What I would like to do instead of using the row number is use the $vin_num value. so if I put ?1FMCU9GD9KUC40413 at the end of the URL it would display the row that contains that Number.
here is the code I have currently, its basically cobbled together from multiple different trends I found so if you notice other potential problems id be happy to hear about them.
<?php
$qstring = $_SERVER['QUERY_STRING'];
$row = $qstring; // The row that will be returned.
$data = get_row('aim-websites-new.csv', $row);
'<pre>'.print_r($data).'</pre>';
function get_row($csv, $row) {
$handle = fopen("$csv", 'r');
$counter = 0;
$result = '';
while ( ($data = fgetcsv($handle)) !== FALSE ) {
$counter++;
if ( $row == $counter ) {
$vin_num="$data[12]";
$model="$data[10]";
$make="$data[9]";
$year="$data[8]";
ob_start();
?>
<h1>VIN: <?php echo $vin_num; ?></h1>
<h1>Year: <?php echo $year; ?></h1>
<h1>Make: <?php echo $make; ?></h1>
<h1>Model: <?php echo $model; ?></h1>
<?php
$output = ob_get_clean();
ob_flush();
return $output;
}
}
}
?>
<?php
function extract_data($file)
{
$raw = file($file); // file() puts each line of file as string in array
$keys = str_getcsv(array_shift($raw)); // extract the first line and convert into an array
// Look through the rest of the lines and combine them with the header
$data = [];
foreach ($raw as $line) {
$row = str_getcsv($line);
$data[] = array_combine($keys, $row);
}
return $data;
}
function get_record($data, $vin)
{
foreach ($data as $record) {
if ($record['VIN'] === $vin)
return $record;
}
return null;
}
$data = extract_data('aim-websites-new.csv');
$vin = $_SERVER['QUERY_STRING'];
if (empty($vin)) {
echo '<h1>No VIN provided</h1>';
exit;
}
$record = get_record($data, $vin);
if ($record === null) {
echo '<h1>No record found</h1>';
exit;
}
echo '<h1>' . $record['VIN'] . '</h1>';
echo '<h1>' . $record['Year'] . '</h1>';
echo '<h1>' . $record['Make'] . '</h1>';
echo '<h1>' . $record['Model'] . '</h1>';
echo '<pre>' . print_r($record, true) . '</pre>';
If you don't trust that the records will have valid VINs, you can use the code posted here to validate: How to validate a VIN number?
I am using the following code to print the output of the jSON response but when I try to print
echo $obj->HotelListResponse->customerSessionId; // This is working.
echo $obj->HotelListResponse->HotelList->HotelSummary->name; // This is not working.
When the response contains only one node then its printing perfectly but when there are multiple nodes with same name then its not printing. I tried using foreach just like the below. I also tried using while loop but still I am unable to print the list of hotel names.
My jSON decoded output is like http://pastebin.com/Fr21DkEk
Total code:
$url = "https://api.eancdn.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=99&apiKey=cbrzfta369qwyrm9t5b8y8kf&locale=en_AU¤cyCode=AUD&xml=<HotelListRequest><city>Brisbane</city><stateProvinceCode>QLD</stateProvinceCode><countryCode>AU</countryCode><arrivalDate>10/16/2014</arrivalDate><departureDate>10/18/2014</departureDate><RoomGroup><Room><numberOfAdults>2</numberOfAdults></Room></RoomGroup><numberOfResults>25</numberOfResults></HotelListRequest>";
$json = file_get_contents($url);
$obj = json_decode($json);
foreach($obj as $val) {
echo $val->HotelListResponse->HotelList->HotelSummary->name;
}
Try this
foreach($obj->HotelListResponse->HotelList->HotelSummary as $val) {
echo $val->name . '<br/>';
}
HotelSummary is an array:
echo $val->HotelListResponse->HotelList->HotelSummary[0]->name;
If you want all of the hotel summaries:
foreach($obj as $val) {
foreach($val->HotelListResponse->HotelList->HotelSummary as $sum) {
echo $sum->name;
}
}
Yes you can directly access them inside the foreach. Like this:
foreach($obj->HotelListResponse->HotelList->HotelSummary as $val) {
// ^^
// since you're interested on just names, you can point it directly on that object, then each of that batch is in `$val`
echo $val->name . '<br/>';
}
// or start from the parent
foreach($obj as $values) {
$customerSessionId = $values->customerSessionId;
echo $customerSessionId . '<hr/>';
$hotelList = $values->HotelList;
foreach($hotelList->HotelSummary as $hotelsummary) {
echo $hotelsummary->name . '<br/>';
}
}
Why i can't get out the values from the json file with PHP?
I get zero values? Have tried for hours.
<?php
$json_string = 'http://pubapi.cryptsy.com/api.php?method=singlemarketdata&marketid=44';
$jsondata = file_get_contents($json_string);
$data = json_decode($jsondata, TRUE);
print_r($data);
echo "<br><br><br><br>";
foreach ($data as $recenttrades) {
echo "VALUES('{$recenttrades->quantity}', '{$recenttrades->price}' ";
}
?>
Update: but can't get the value from primaryname and primarycode.
I have tried this:
$json_string = 'http://pubapi.cryptsy.com/api.php?method=marketdatav2';
$jsondata = file_get_contents($json_string);
$data = json_decode($jsondata, TRUE);
//print_r($data);
foreach ($data["market"] as $markets) {
echo "Primary code: <strong>{$markets['primarycode']}</strong><br>";
foreach($markets as $market) {
foreach($market as $attributes) {
foreach($attributes["recenttrades"] as $recenttrade) {
echo "quantity: " . $recenttrade['quantity'] .", price: " . $recenttrade['price'] . "<br>";
}
}
}
}
Others have mentioned that you're dealing with nested arrays, not objects. Along with pointing out the issue of being nested rather deeply, I would suggest digging down with foreach (I will probably be crucified for this):
<?php
$json_string = 'http://pubapi.cryptsy.com/api.php?method=singlemarketdata&marketid=44';
$jsondata = file_get_contents($json_string);
$data = json_decode($jsondata, TRUE);
//print_r($data);
echo "<br><br><br><br>";
foreach ($data as $markets) {
foreach($markets as $market) {
foreach($market as $attributes) {
foreach($attributes["recenttrades"] as $recenttrade) {
//echo "<pre>";
//print_r($recenttrade);
//echo "</pre>";
echo "VALUES('{quantity: " . $recenttrade['quantity'] ."}', 'price: {" . $recenttrade['price'] . "}')";
}
}
}
}
?>
This will ensure that you grab every recentrades item at this level of the array. This way you are prepared for other markets to be added to the API and your code isn't locked into searching only in the item named "FST".
recenttrades is nested pretty deeply in that array. Try
foreach ($data['return']['markets']['FST']['recenttrades'] as $recenttrades) {
recenttrades is several levels nested, so simply doing foreach($data as $recenttrades) is not sufficient.
You need to do:
$recentTrades = $data['return']['markets']['FST']['recenttrades'];
foreach($recentTrades as $recentTrade) {
...
}
recenttrades is nested deeply and you're asking for arrays, not objects. This seems to work:
foreach ($data['return']['markets']['FST']['recenttrades'] as $recenttrades) {
echo "VALUES('{$recenttrades['quantity']}', '{$recenttrades['price']}' ";
}
In response to your update, where you want to loop over markets, try this:
foreach ($data['return']['markets'] as $market) {
echo "Primary code: <strong>{$market['primarycode']}</strong><br>";
foreach ($market["recenttrades"] as $recenttrade) {
echo "quantity: " . $recenttrade['quantity'] .", price: " . $recenttrade['price'] . "<br>";
}
}
Could someone help me with this?
I have a folder with some files (without extention)
/module/mail/templates
With these files:
test
test2
I want to first loop and read the file names (test and test2) and print them to my html form as dropdown items. This works (the rest of the form html tags are above and under the code below, and omitted here).
But I also want to read each files content and assign the content to a var $content and place it in an array I can use later.
This is how I try to achieve this, without luck:
foreach (glob("module/mail/templates/*") as $templateName)
{
$i++;
$content = file_get_contents($templateName, r); // This is not working
echo "<p>" . $content . "</p>"; // this is not working
$tpl = str_replace('module/mail/templates/', '', $templatName);
$tplarray = array($tpl => $content); // not working
echo "<option id=\"".$i."\">". $tpl . "</option>";
print_r($tplarray);//not working
}
This code worked for me:
<?php
$tplarray = array();
$i = 0;
echo '<select>';
foreach(glob('module/mail/templates/*') as $templateName) {
$content = file_get_contents($templateName);
if ($content !== false) {
$tpl = str_replace('module/mail/templates/', '', $templateName);
$tplarray[$tpl] = $content;
echo "<option id=\"$i\">$tpl</option>" . PHP_EOL;
} else {
trigger_error("Cannot read $templateName");
}
$i++;
}
echo '</select>';
print_r($tplarray);
?>
Initialize the array outside of the loop. Then assign it values inside the loop. Don't try to print the array until you are outside of the loop.
The r in the call to file_get_contents is wrong. Take it out. The second argument to file_get_contents is optional and should be a boolean if it is used.
Check that file_get_contents() doesn't return FALSE which is what it returns if there is an error trying to read the file.
You have a typo where you are referring to $templatName rather than $templateName.
$tplarray = array();
foreach (glob("module/mail/templates/*") as $templateName) {
$i++;
$content = file_get_contents($templateName);
if ($content !== FALSE) {
echo "<p>" . $content . "</p>";
} else {
trigger_error("file_get_contents() failed for file $templateName");
}
$tpl = str_replace('module/mail/templates/', '', $templateName);
$tplarray[$tpl] = $content;
echo "<option id=\"".$i."\">". $tpl . "</option>";
}
print_r($tplarray);
I have an array coming from a .csv file. These are coming from a real estate program. In the second column I have the words For Sale and in the third column the words For Rent that are indicated only on the rows that are concerned. Otherwise the cell is empty. I want to display a list rows only For Sale for example. Of course then if the user clicks on a link in one of the rows, the appropriate page will be displayed.
I can't seem to target the text in the column, and I can't permit that the words For Sale be used throughout the entire array because they could appear in another column (description for example).
I have tried this, but to no avail.
/* The array is $arrCSV */
foreach($arrCSV as $book) {
if($book[1] === For Sale) {
echo '<div>';
}
echo '<div>';
echo $book[0]. '<br>';
echo $book[1]. '<br>';
echo $book[2]. '<br>';
echo $book[3]. '<br>';
echo $book[6]. '<br><br><br>';
echo '</div>';
}
I also tried this:
foreach($arrCSV as $key => $book) {
if($book['1'] == 'For Sale') {
echo '<div>';
}
echo '<div>';
echo $book[0]. '<br>';
echo $book[1]. '<br>';
echo $book[2]. '<br>';
echo $book[3]. '<br>';
echo $book[6]. '<br><br><br>';
echo '</div>';
}
Do you mean:
foreach($arrCSV as $key => $book) {
if($book['1'] == 'For Sale') {
echo '<div></div>';
}else{
echo '<div>';
echo $book[0]. '<br>';
echo $book[1]. '<br>';
echo $book[2]. '<br>';
echo $book[3]. '<br>';
echo $book[6]. '<br><br><br>';
echo '</div>';
}
}
I found a solution here:
PHP: Taking Array (CSV) And Intelligently Returning Information
$searchCity = 'For Sale'; //or whatever you are looking for
$file = file_get_contents('annonces.csv');
$results = array();
$lines = explode("\n",$file);
//use any line delim as the 1st param,
//im deciding on \n but idk how your file is encoded
foreach($lines as $line){
//split the line
$col = explode(";",$line);
//and you know city is the 3rd element
if(trim($col[1]) == $searchCity){
$results[] = $col;
}
}
And then:
foreach($results as $Rockband)
{
echo "<tr>";
foreach($Rockband as $item)
{
echo "<td>$item</td>";
}
echo "</tr>";
}
