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
Code: Select all
$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;

Hi semantic
If you say it all works already, it sounds like you've just got the third loop in the wrong place. Try moving it to within your second while loop:
Code: Select all
$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
$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
$inner=$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($value);
}
}
}
}// while
mysql_close($conn);
$xml_string = $doc->saveXML();
echo $xml_string;
