hay gays i want to retrieve xml data from three table stored in mysql.
i used the below code it works fine but first it retrieve one record
from first table than iterate to second table and print the whole
table and then iterate to third table and print the whole table but i
want to print first table along with relevant records in second table
(not whole table) then from third table and so on. my code is
$table_first = 'recipe';
$query = "SELECT * FROM $table_first";
$resouter = mysql_query($query, $conn);
$table_second='instructions';
$query="SELECT
instructions.instruction_id,instructions.instruction_text FROM
$table_second";
$resinner=mysql_query($query, $conn);
$table_third='ingredients';
$query="SELECT
ingredients.ingredient_id,ingredients.ingredient_name,ingredients.ammount
FROM $table_third";
$resthird=mysql_query($query, $conn);
$doc = new DomDocument('1.0');
$root = $doc->createElement('recipes');
$root = $doc->appendChild($root);
while($row = mysql_fetch_assoc($resouter)){
$outer = $doc->createElement($table_first);
$outer = $root->appendChild($outer);
foreach ($row as $fieldname => $fieldvalue) {
$child = $doc->createElement($fieldname);
$child = $outer->appendChild($child);
$value = $doc->createTextNode($fieldvalue);
$value = $child->appendChild($value);
}// foreach
//while
$inner = $doc->createElement($table_second);
$inner = $outer->appendChild($inner);
while($row = mysql_fetch_assoc($resinner)){
// add node for each record
$inner1=$doc->createElement('instruction');
$inner1=$inner->appendChild($inner1);
// add a child node for each field
foreach ($row as $fieldname => $fieldvalue) {
$child = $doc->createElement($fieldname);
$child = $inner1->appendChild($child);
$value = $doc->createTextNode($fieldvalue);
$value = $child->appendChild($value);
} // foreach
}// while
$inner=$doc->createElement($table_third);
$inner=$outer->appendChild($inner);
while($row=mysql_fetch_assoc($resthird)){
$inner2=$doc->createElement('ingredient');
$inner2=$inner->appendChild($inner2);
foreach($row as $fieldname=> $fieldvalue)
{
$child=$doc->createElement($fieldname);
$child=$inner2->appendChild($child);
$value=$doc->createTextNode($fieldvalue);
$value=$child->appendChild($value);
}
}
}
mysql_close($conn);
$xml_string = $doc->saveXML();
echo $xml_string;

But, at first, he should understand what his PHP-code does,
before he can realize that he has a problem with his SQL
