I have the following XML file
<study>

<s3_fifth name="Michael C. Two">Scenario 3 5th developer</s3_fifth>
</scenario_3>
</study>
And, I'm using the following PHP code to print names and values of "scenario_2"'s children
$xml_temp = simplexml_load_file("db/temp.xml");
$scenarios = $xml_temp -> children();
foreach( $scenarios[2] -> children() as $scenario_2_developer){
echo $scenario_2_developer['name']. ": " . $scenario_2_developer -> nodeValue;
It prints the attributes perfectly BUT NOT the VALUE. How can I fix it, so it prints the VALUE of the node as well?
You are pretty close, however with SimpleXML there is not ->nodeValue property, just cast the element object to string and you're fine:
echo $scenario_2_developer['name'], ": ", $scenario_2_developer, "\n";
^
|
echo casts this object to string
But I really wonder who creates such an XML, numbering element names that way seems pretty counter-productive. The XML should be fixed for better use.
Every SimpleXMLElement has a property innerNode. Cast that to a string and it will be the value you're looking for.

I am trying to use the tablesorter pager plugin with AJAX but run into som problemes (or limitations) when trying to handle the AJAX request in my php backend.
If eg. the table is set up with a default sorting of
sortList: [ [0,1], [1,0] ]
I will get a URL like this on my AJAX request:
page=0&size=50&filter=fcol[6]=batteri&sort=col[0]=1&col[1]=0
In my php back end I do a
$cur_sort = $_GET['sort']
and get
col[0]=1
So the last part is missing - I guess since it contains a & char.
How do I get the entire sort string?
That said how is the string col[0]=1&col[1]=0 best parsed? I need to extract the info that col 0 is to be sorter DESC and col 1 ASC.
You can try this;
parse_str($_SERVER['QUERY_STRING'],$data);
It will parse the url to an array;
Also; you should use empty [] instead of [1] and [0]
See more here: parse_str()
Example:
$str = "page=0&size=50&filter=fcol[6]=batteri&sort=col[0]=1&col[1]=0";
parse_str($str, $output);
echo $output['page']; // echo 0
And to answer your question; it is correct; is echoing col[0]=1 because you are dividing with & see here:
&sort=col[0]=1 & col[1]=0;
An advice; use more names, instead.
You could use
&sort[]=1&sort[]=0;
UPDATE:
To access the last one; you should do, simply;
$_GET['col'][1];
If you want to access, the last number in
$_GET['sort'];
You can do this;
$explode = explode('=',$_GET['sort']);
$end = end($explode);
echo $end; //it will outout 1
If you print your entire query_String, it will print this;
Array
(
[page] => 0
[size] => 50
[filter] => fcol[6]=batteri
[sort] => col[0]=1
[col] => Array
(
[1] => 0
)
)
I'm not sure how the ajaxUrl option is being used, but the output shared in the question doesn't look right.
I really have no idea how the string in the question is showing this format:
&sort=col[0]=1&col[1]=0 (where did sort= come from?)
&filter=fcol[6]=batteri (where did filter= come from?)
If you look at how you can manipulate the ajaxUrl option, you will see this example:
ajaxUrl: "http://mydatabase.com?page={page}&size={size}&{sortList:col}&{filterList:fcol}"
So say you have the following settings:
page = 2
size = 10
sortList is set to [[0,1],[3,0]] (1st column descending sort, 4th column ascending sort)
filters is set as ['','','fred']
The resulting url passed to the server will look like this:
http://mydatabase.com?page=2&size=10&col[0]=1&col[3]=0&fcol[2]=fred
The col part of the {sortList:col} placeholder sets the sorted column name passed to the URL & the fcol part of {filterList:fcol} placeholder sets the filter for the set column. So those are not fixed names.
If the above method for using the ajaxUrl string doesn't suit your needs, you can leave those settings out of the ajaxUrl and instead use the customAjaxUrl option to modify the URL as desired. Here is a simple example (I know this is not a conventional method):
ajaxUrl: "http://mydatabase.com?page={page}&size={size}",
// modify the url after all processing has been applied
customAjaxUrl: function(table, url) {
var config = table.config,
// convert [[0,1],[3,0]] into "0-1-3-0"
sort = [].concat.apply( [], config.sortList ).join('-'),
// convert [ '', '', 'fred' ] into "--fred"
filter = config.lastSearch.join('-');
// send the server the current page
return url += '&sort=' + sort + '&filter=' + filter
}
With the same settings, the resulting URL will now look like this:
http://mydatabase.com?page=2&size=10&sort=0-1-3-0&filter=--fred
This is my own best solution so far, but it's not really elegant:
if (preg_match_all("/[^f]col\[\d+]=\d+/", $_SERVER['QUERY_STRING'], $matches)) {
foreach($matches[0] AS $sortinfo) {
if (preg_match_all("/\d+/", $sortinfo, $matches)) {
if(count($matches[0]) == 2) {
echo "Col: ".$matches[0][0]."<br/>";
echo "Order: ".$matches[0][1]."<br/>";
}
}
}
}
It gives me the info I need
Col: 0
Order: 1
Col: 1
Order: 0
But is clumbsy. Is there a better way?
I try to get the child id's of products dynamically.Below is my table structure.
parent|child
---------------------
44 | 35,6,47,5,50
---------------------
47 | 8,9
---------------------
50 | 12, 15
am going to pass only one parent id and get the child ids, and if anyone of child ids having again child, then i have to fetch that record also.example 44->35,6,47,5,50 in this 47 and 50 is having child ids, so my final output should be like this 44-> 35,6,47,8,9,5,50,12,15.
I tried below this,
$sql=mysql_fetch_assoc(mysql_query("select * from chain_product where parent='44'"));
$parent=$sql['parent'];
$child=$sql['child'];
$ex=explode(",",$child);
$count=sizeof($ex);
for($i=0;$i<$count;$i++)
{
$list=add_child($ex[$i],$child);
$check=explode(",",$list);
$chck_count=sizeof($check);
if($chck_count>$count)
{
$exit=add_child($ex[$i],$list);
print_r($exit);
}
}
function add_child($main,$ch)
{
$find=mysql_query("select * from chain_product where parent='$main'");
$res=mysql_fetch_assoc($find);
if($res)
{
$replace=$main.",".$res['child'];
$alter=str_replace($main,$replace,$ch);
echo $alter;
}
}
but i get the result like this,
35,6,47,8,9,5,5035,6,47,5,50,12,15
but i need output should be like this..
35,6,47,8,9,5,50,12,15.
can anyone help me to do this..
Your database structure isnt optimal for this, this would be better:
id | parent
1 | 0
2 | 1
3 | 1
4 | 2
5 | 2
This way you can do something recursive:
function getChilds($parent=0, $depth=0){
// Select the items for the given $parent
$query = $conn->mysqli_query("SELECT id WHERE parent=".$parent); // mysqli is better, but mysql will do fine
// get the items by the parent giving as input:
while($fetch = $query->fetch_assoc() ){
echo str_repeat('-', $depth) . " ".$fetch['id'];
getChilds($fetch['id'], $depth+1); // Use id of this line to find its childs
echo "<br />";
}
}
getChilds(0); // And start it. The 0 is optional, I personaly prefer -1. Whatever rows your boat
This is called a tree structure and should give something like this:
1
- 2
- - 4
- - 5
- 3
In this example I use an echo for display purposes, you can return the values via an array, same principle
To answer a bit better, your current structure could support a similar method, but because you use strings, it will be allow slower and alot less flexible. You can see the difference in the code you are using, and the amount I just used. If you would remove the echo's and only return arrays, it will be even smaller :)
Thanks in advance for any help offered.
I'm performing a query that returns something like this:
route | busnumber
2 300
4 123
2 455
12 934
My goal is to print/echo a list of all "busnumber" were "route" = 2.
I know I can do a query on the DB to do this but I don't want to run this query for each and every route. The result set is actually part of one master, complex query so I need to accomplish my goal using the array.
The query works correctly and does display the appropriate info. I also return the results into an array. i.e ...
$query=("SELECT * from foo")
$result=mysql_fetch_assoc($query);
My current code looks like this (note my comments):
mysql_data_seek( $result,0); // because I'm previously iterating through $result
while ($i2=mysql_fetch_assoc($result)) {
$busnumber=$i2['busnumber'];
$busroute=$i2['route'];
echo "<div class='businfo'>";
if ($busroute='2'){ // I only want this to happen if $busroute=2
echo "Current Route = $busroute</br>";
echo "Bus Number : $busnumber </br>";
}
echo "</div>";
}
What I'm getting, however, it is echoing the same '$busroute' (2) but different '$busnumber' for each row as such:
Current Route = 2
Bus Number : 194
Current Route = 2
Bus Number : 196
Current Route = 2
Bus Number : 2002
Current Route = 2
Bus Number : 2010
Current Route = 2
Bus Number : 2013
The problem is that all of those bus numbers are not part of route 2. It is a listing of bus numbers from all routes. I only want it to perform the foreach loop if $routenumber=2.
Thanks again for the help :)
if ($busroute='2'){
The problem is that you're not checking whether it's equal to 2 here, you're assigning it to equal 2. Change it to this and you'll be fine:
if ($busroute=='2'){
$query = "SELECT * from foo";
$result = mysql_query($query);
while($row = mysql_fetch_assoc($result)) {
if ($row['route'] == 2) {
// do your stuff
}
}
I am having an issue wrapping my head around the SimpleXML syntax.
I am trying to echo a few pieces of info I pull out of a larger xml document based on a predefined value DELN:
$mytimes= simplexml_load_file('http://www.bart.gov/dev/eta/bart_eta.xml');
$freemont = $mytimes->station->abbr[DELN]->eta->destination[freemont]->estimate;
$millbrae = $mytimes->station->abbr[DELN]->eta->destination[millbrae]->estimate;
$richmond = $mytimes->station->abbr[DELN]->eta->destination[richmond]->estimate;
My XML:
<station>
<name>El Cerrito del Norte</name>
<abbr>DELN</abbr>
<date>11/30/2012</date>
<time>07:41:02 AM PST</time>
<eta>
<destination>Fremont</destination>
<estimate>14 min, 29 min, 44 min</estimate>
</eta>
<eta>
<destination>Millbrae</destination>
<estimate>6 min, 21 min, 36 min</estimate>
</eta>
<eta>
<destination>Richmond</destination>
<estimate>4 min, 10 min, 17 min</estimate>
</eta>
</station>
Let me know if I need to provide more info. Thanks.
First - I suppose you're not defining DELN constant, probably you should use a string ('DELN'). Same with freemont, millbrae and richmont. The problem is not only SimpleXML syntax, basically its misunderstanding of XML structure that you want to read (abbr is not in straight path with eta, same with destination and estimate). Anyway - xpath will be your friend here:
$fremont = $mytimes->xpath('//station/eta/estimate[../../abbr/text()=\'DELN\' and ../destination/text()=\'Fremont\']');
$millbrae = $mytimes->xpath('//station/eta/estimate[../../abbr/text()=\'DELN\' and ../destination/text()=\'Millbrae\']');
$richmond = $mytimes->xpath('//station/eta/estimate[../../abbr/text()=\'DELN\' and ../destination/text()=\'Richmond\']');
then you can do:
foreach ($fremont as $value) echo $value;
or just
if (count($fremont) > 0) echo $fremont[0];
I have a table comment as follow:
Comment
comment_id cmt followupid
1 Hello 3
2 hi 4
3 Hey 2
4 wassup 1
My query is that I want to echo "Hello", "hi", "hey" , "Wassup" and other (the record continues) individualy, I have used
$comment = mysql_result($runQuery, $i,"cmt");
echo $comment;
which works fine but the problem is that it echoes all the comments at once, what I want is to echo all the comment but one at a time. the comment are in a div tag such that each the div appears only after 1 second the page is loaded. I want each comment to appear after different time interval
for e.g:
Hello to appear at 5pm (not necessarily the corect time it can be just an int)
hi 5.10 pm
hey 6.30 pm
Please Help!
The following code should give you some hints.
$result = mysql_query($runquery);
while($row=mysql_fetch_assoc($result)){
// $row contains a single row.
echo $row['cmt'], $row['comment_id']
}
Create another variable storing time divisions(or number of rows). So that different output at different time can be fetched. For eg. If your table has 24 rows(or items), then this variable shall have a value 24. Use it to divide you output times(As in 24 hours, each hour a different value).
Now, the PHP part(I am not much familiar with date and time functions in PHP, so you can totally ignore the paragraph above.
$result = mysql_query($runquery);
$j = 0;
$i = rand( 0, mysql_num_rows($result) );
while($row=mysql_fetch_assoc($result)){
// $row contains a single row.
if( $j++ = $i )
echo $row['cmt'], $row['comment_id'];
}
This will fetch one random row from the table, but not depending upon the server time.
