I have included my PHP code with a snippet of the XML file I am retrieving data from.
I want to display the data from the XML file similar to how I used it as an ID. Within the ID it uses the ID as an index however I see that it won't work as a date.
My first idea was to just use xPath and leave it as this but I would like to format my data similar for consistency.
As a beginner with PHP and XML any insight or documentation that could further my studying with either the language or the format style would be appreciated.
The problem I am having is to find the index value of the relevant attribute that has been inputted and outputting it individually in a format such as the ID Search.
<?php
if($_GET["SearchChoice"] == "ID Search"){ #WORKING FINDS THE VALUE OF DATA NEEDED
$xml=simplexml_load_file("XMLtest.xml") or die("Error: Cannot create object");
$passID = intval($_GET["IDsend"]);
if ($passID !== 0){
$passID = $passID - 1;
}
#echo $xml['date'];
#echo var_dump((string)$xml['date']);
$attr = $xml->finances[$passID]->attributes();
echo "Date: ";
echo $attr['date'];
echo $xml->finances[$passID]->day . ",<br>Projection: ";
echo $xml->finances[$passID]->projection . ",<br>Recommended Staff: ";
echo $xml->finances[$passID]->recommendedStaff . ",<br>Staff Wages: ";
echo $xml->finances[$passID]->staffWages . ",<br>Actual: ";
echo $xml->finances[$passID]->actual . "<br>";
}
elseif($_GET["SearchChoice"] == "Date Search") {
$xml=simplexml_load_file("XMLtest.xml") or die("Error: Cannot create object");
$passDate = strval($_GET["DateSend"]);
$nodes = $xml->xpath("/january/finances[@date='". $passDate . "']"); # Instead of xpath possiblity: loop through to find date then output it similar to ID Search?
print_r($nodes);
}
else {
echo "Error 1 <br>";
echo $_GET["SearchChoice"];
}
Here is a portion of the XML:
<?xml version="1.0" encoding="UTF-8"?>
<january>
<finances id="1" date="01-01-2016">
<projection>414</projection>
<recommendedStaff>20</recommendedStaff>
<staffWages>100</staffWages>
<actual>250</actual>
</finances>
<finances id="2" date="02-01-2016">
<year>2016</year>
<month>01</month>
<day>02</day>
<projection>124</projection>
<recommendedStaff>8</recommendedStaff>
<staffWages>150</staffWages>
<actual>250</actual>
</finances>
<finances id="3" date="03-01-2016">
<projection>687</projection>
<recommendedStaff>20</recommendedStaff>
<staffWages>150</staffWages>
<actual>250</actual>
</finances>
<finances id="4" date="04-01-2016">
<projection>587</projection>
<recommendedStaff>15</recommendedStaff>
<staffWages>150</staffWages>
<actual>250</actual>
</finances>
<finances id="5" date="05-01-2016">
<projection>124</projection>
<recommendedStaff>5</recommendedStaff>
<staffWages>150</staffWages>
<actual>250</actual>
</finances>
<finances id="6" date="06-01-2016">
<projection>874</projection>
<recommendedStaff>22</recommendedStaff>
<staffWages>150</staffWages>
<actual>250</actual>
</finances>
</january>
$xml=simplexml_load_file("XMLtest.xml") or die("Error: Cannot create object");
switch ($_GET["SearchChoice"])
{
case 'ID Search':
$nodes = $xml->finances[$passID];
break;
case 'Date Search':
$passDate = strval($_GET["DateSend"]);
$nodes = $xml->xpath("/january/finances[@date='". $passDate . "']");
if ($nodes)
$nodes = array_shift($nodes); // First match
break;
default:
$nodes = NULL;
}
if ($nodes) // Don't care how we got them
{
echo $nodes->day . ",<br>Projection: ";
// etc
}
This loads the file at the start and then creates a node (stored in $nodes) based on your search choice (familiarize yourself with switch statements - very useful, especially the "break" command when it's used or not used).
After the switch statement, you have a node regardless of how you got it. That's good practice in coding - the condition is "taken care of" and from here on out is not an issue.
In actuality, it might be a better idea to just use xpath for both options - minimal difference between the different code paths makes for easier debugging and maintenance.
