I'm trying to return the inserted id from a mysql INSERT query. Each time I run the function I get 0 as the result. Can someone please explain at what point I can retrieve the value because although the script below executes I cannot retireve the inserted id. Probably done something stupid.
<?php
public function execSQL($sql, $params, $close){
$mysqli = new mysqli(DB_HOST,DB_USER,DB_PASSWORD,DB_NAME);
$stmt = $mysqli->prepare($sql) or die ("Failed to prepared the statement!");
call_user_func_array(array($stmt, 'bind_param'), $this->refValues($params));
$this->insert_id($this->connection);
$stmt->execute();
if($close){
$result = $mysqli->affected_rows;
} else {
$meta = $stmt->result_metadata();
while ( $field = $meta->fetch_field() ) {
$parameters[] = &$row[$field->name];
}
call_user_func_array(array($stmt, 'bind_result'), $this->refValues($parameters));
while ( $stmt->fetch() ) {
$x = array();
foreach( $row as $key => $val ) {
$x[$key] = $val;
}
$results[] = $x;
}
$result = $results;
}
$stmt->close();
$mysqli->close();
return $result;
}
?>
Check $mysqli->insert_id after executing insert query.

I tried different possibilities but nothing worked, in the tutorial I couldn't find an example either.
I have a method in my modelclass:
public function getlastImport($filename)
{
//$id = (int) $id;
$rowset = $this->tableGateway->select(['Path' => $filename]);
$row = $rowset->current();
if (! $row) {
throw new RuntimeException(sprintf(
'Could not find row with identifier %d',
$id
));
}
return $row;
}
I want to retrieve the last import of a given filename, so ist must be like in sql:
select max(ID) from table where filename = $filename;
But how would be the right syntax in this case?
The sql query should be
"SELECT * FROM table_name WHERE filename={$filename} ORDER BY id DESC LIMIT 1"
Use as the following in your model
public function getlastImport($filename)
{
$select = $this->tableGateway->getSql()->select();
$select->columns(array('id', 'filename', 'label'));
$select->where(array('filename' => $filename));
$select->order("id DESC");
$select->limit(1);
$result = $this->tableGateway->selectWith($select);
$row = $result->current();
if (! $row) {
throw new RuntimeException(sprintf(
'Could not find row with identifier %d',
$id
));
}
return $row;
}
Hope this would help you!
I'm trying to use PDO using the following code, I want to select the array of values for the context_list, but it returns one record, any ideas where I'm going wrong?
try {
$sql2 = "SELECT area_easting, area_northing, context_number FROM excavation.contexts";
$sth = $conn->prepare($sql2);
$sth->execute();
while ($row = $sth->fetch(PDO::FETCH_ASSOC))
{
$easting_list = $row['area_easting'];
$northing_list = $row['area_northing'];
$context_list = $row['context_number'];
}
}
catch(PDOException $e )
{
echo "Error: ".$e;
}
echo "context list: ";
echo $context_list;
A partial solution:
This worked:
$query = $conn->prepare("SELECT area_easting, area_northing, context_number FROM excavation.contexts");
$query->execute();
while($r = $query->fetch(PDO::FETCH_OBJ)){
echo $r->area_easting, '|';
echo $r->area_northing;
echo '<br/>';
}
But Now I need to make the $r->area_easting accessible to the session, but that's another question.
Your query may return several records (provided they actually exist in the table).
Your code loops through all the records (with the while loop) but the values ($easting_list, $northing_list and $context_list) are overwritten in the loop.
I suggest the following changes to your code:
$easting_list = array();
$northing_list = array();
$context_list = array();
try {
$sql2 = "SELECT area_easting, area_northing, context_number FROM excavation.contexts";
$sth = $conn->prepare($sql2);
$sth->execute();
while ($row = $sth->fetch(PDO::FETCH_ASSOC))
{
$easting_list[] = $row['area_easting'];
$northing_list[] = $row['area_northing'];
$context_list[] = $row['context_number'];
}
}
catch(PDOException $e )
{
echo "Error: ".$e;
}
echo "context list: ";
echo implode(', ', $context_list);
Now all the values are stored in 3 arrays. explode is used to print a comma-separated list of all values in $context_list array.
I have a problem and don't know how to solve it. After i run the code i didn't receive corectly a period of time. I put the code here.
I think something is wrong with table from database (i use PhpMyAdmin 4.2.0 module from EasyPhp). I put an image too to see what happens. The dates marked with red need to be at the end of table.
<?php
function data_range($first, $last, $step = '+1 day', $output - format = 'd-m-Y')
{
$dates = array();
$current = strtotime($first);
$last = strtotime($last);
while ($current <= $last)
{
$dates[] = date($output_format, $current);
$current = strtotime($step, $current);
}
foreach($dates as $zile)
{
$krr = explode('-', $zile);
var_dump($krr);
$result2 = implode('/', $krr);
echo $result2 . "<br/>";
$sql4 = "INSERT INTO studenti3 (data) VALUES ('$result2')";
$rez4 = mysql_query($sql4);
}
var_dump($dates);
}
$first = "06-04-2015";
$last = "07-05-2015";
$step = "+1day";
$output_format = 'd-m-Y';
date_range($first, $last, $step, $output_format); ?>
sub loadFileRecon {
my $self = shift;
my $days = shift;
if($days eq '') {
$days = 1;
}
my $insert = $self->{rba}->rbdb->prepare(q{
insert into rba.filerecon (
filename,
records,
start_dtm,
file_type,
managed_file_id,
mf_dtm,
processed_tidemark,
mm_records,
mm_dropped,
mm_erred,
mm_duplicate,
file_source
)
select
i.filename,
i.records,
i.file_dtm start_dtm,
i.file_type,
mf.managed_file_id,
mf.created_dtm mf_dtm,
NULL,
i.orig_records,
i.dropped,
i.erred,
i.duplicate,
i.file_source
from rba.mmfilestats i, managedfile mf, filelog fl
where
i.filename = fl.file_name and
trunc(i.file_dtm) = trunc(sysdate - ?) and
mf.managed_file_id = fl.managed_file_id
}) or die $DBI::errstr;
$insert->execute($days);
$insert->finish;
$self->{rba}->rbdb->commit;
my $update = $self->{rba}->rbdb->prepare(q{
update rba.filerecon fr
set processed_tidemark = (
select processed_tidemark
from jobhasfile j
where j.managed_file_id = fr.managed_file_id
)
where
trunc(start_dtm) = trunc(sysdate - ?) and
processed_tidemark is null
});
$update->execute($days);
$insert->finish;
$self->{rba}->rbdb->commit;
}
If the prepare statement above fails due to table or view not existing, then it should return a value to perl module
you are telling your program to die if the prepare returns false:
}) or die $DBI::errstr;
replace that with what you're looking for:
}) or return $somevalue;
or remove the or entirely and check the value of your statement handle;
my $insert = $self->{rba}->rbdb->prepare(q{
...
});
return $somevalue if ( !$insert );
What you need to do is return the DBI::errstr. Do not die on error.
So do something like this (starting at your prepare and ending with your where but getting rid of the "or die"):
...prepare( ......
where
i.filename = fl.file_name and
trunc(i.file_dtm) = trunc(sysdate - ?) and
mf.managed_file_id = fl.managed_file_id
});
if ($DBI::errstr) {
# oops something is wrong
print $DBI::errstr;
call_error($DBI::errstr);
}
Good luck
Your post of the errorlog shows that your error is raised at point of execute not at the point of prepare.
So this what you do AFTER the execute:
#your execute statement first
$insert->execute($days);
#Now the check on the execute
if ($DBI::errstr) {
# oops something is wrong
return -1;
}
Please let me know if this works
I am using the following code to list all the manufacturers and it works like a charm:
$attribute = Mage::getModel('eav/entity_attribute')
->loadByCode('catalog_product', 'manufacturer');
$valuesCollection = Mage::getResourceModel('eav/entity_attribute_option_collection')
->setAttributeFilter($attribute->getData('attribute_id'))
->setStoreFilter(0, false);
$preparedManufacturers = array();
foreach($valuesCollection as $value) {
$preparedManufacturers[$value->getOptionId()] = $value->getValue();
}
if (count($preparedManufacturers)) {
echo "<h2>Manufacturers</h2><ul>";
foreach($preparedManufacturers as $optionId => $value) {
echo "<li>" . $value . " - (" . $optionId . ")</li>";
}
echo "</ul>";
}
What I am looking for is a way to display the number of products associated with each of the manufacturers. Can someone please tell me the way of doing this?
Many thanks
Not all mine, but works for me in 1.6+?
<?php
include_once 'app/Mage.php';
Mage::app();
$attribute = Mage::getModel('eav/entity_attribute')
->loadByCode('catalog_product', 'manufacturer');
$valuesCollection = Mage::getResourceModel('eav/entity_attribute_option_collection')
->setAttributeFilter($attribute->getData('attribute_id'))
->setStoreFilter(0, false);
$preparedManufacturers = array();
foreach ($valuesCollection as $value) {
$preparedManufacturers[$value->getOptionId()] = $value->getValue();
}
if (count($preparedManufacturers)) {
echo "<h2>Manufacturers</h2><ul>";
foreach ($preparedManufacturers as $optionId => $value) {
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addFieldToFilter(array(array('attribute' => 'manufacturer', 'eq' => $optionId)));
$mumberOfProducrt = count($collection);
echo "<li>" . $value . " - (" . $mumberOfProducrt . ")</li>";
}
echo "</ul>";
}
?>
This would work but won't be the most efficient:
foreach($valuesCollection as $value) {
$preparedManufacturers[$value->getOptionId()] = $value->getValue();
$collection = Mage::getModel('catalog/product')->getCollection();
$collection
->addAttributeToSelect('*') // '*' not efficient though
->addAttributeToFilter('manufacturer', array('eq' => $value->getOptionId()))
//->addAttributeToFilter('manufacturer', $value->getOptionId())
;
$count = $collection->->getSize();
}
It's an extra query for each manufacturer so it's not great, if you have some caching etc it won't be too bad though.
Working code should do it
$collection = Mage::getModel('catalog/product')->getCollection()->groupByAttribute('manufacturer')
->addFieldToFilter('status',Mage_Catalog_Model_Product_Status::STATUS_ENABLED)
->addExpressionAttributeToSelect("count",'COUNT({{entity_id}})', 'entity_id');
Mage::getSingleton('cataloginventory/stock')->addInStockFilterToCollection($collection);
