I am trying to using this API. https://www.blocktrail.com/api/docs I can retrieve the first layer value using this. $global_trans_id = $client->transaction($post_transid); $api_transaction_id = $global_trans_id['hash']; echo $api_transaction_id; As you see "hash" is the first layer below. But what if I want to retrieve the second layer such as a value from "Inputs" or "Outputs" like "$global_trans_id['address'];". How would that look? { "hash": "c326105f7fbfa4e8fe971569ef8858f47ee7e4aa5e8e7c458be8002be3d86aad", "first_seen_at": "2014-03-11T08:27:57+0000", "last_seen_at": "2014-03-11T08:27:57+0000", "block_height": 290000, "block_time": "2014-03-11T08:27:57+0000", "block_hash": "0000000000000000fa0b2badd05db0178623ebf8dd081fe7eb874c26e27d0b3b", "confirmations": 31130, "is_coinbase": false, "estimated_value": 70000000, "total_input_value": 70070000, "total_output_value": 70030000, "total_fee": 40000, "estimated_change": 30000, "estimated_change_address": "19M1EraiuAvZp8ZV7QJHH2LVkYm8ECufCJ", "high_priority": false, "enough_fee": true, "contains_dust": false, "inputs": [ { "index": 0, "output_hash": "d283ab6edd394b8a69d6943ea3a29a679d92176b112b1f69ffb9b70cf27dec5a", "output_index": 2769, "value": 2730000, "address": "19M1EraiuAvZp8ZV7QJHH2LVkYm8ECufCJ", "type": "pubkeyhash", "multisig": null, "script_signature": "0x49 0x3046022100bb3d102afd0d57be618aeaa7432bc038dea928bec0af6b8cba37c7ec85701e3d022100c467073956b385f08fbfbc2e130d8f76deb7c5436ba245afca4678200b127c2001 0x21 0x02aa6584518e528be497be65fba84913b7d0cb55158f4e7922298923286a7f6156" }, { "index": 1, "output_hash": "b350de75f9c27b457fa6cefb7072af8aa94de53ccedff4ec06ce885d63645e1d", "output_index": 2764, "value": 2740000, "address": "19M1EraiuAvZp8ZV7QJHH2LVkYm8ECufCJ", "type": "pubkeyhash", "multisig": null, "script_signature": "0x48 0x3045022059c6cc77c0a7c3a3a1ab0678690178750f2b5e442dc6f9331835be4cdb087cc00221008fca79860ab8f15acba61522b4f8482909cadfdf79dca7790efabf71c7c12d3701 0x21 0x02aa6584518e528be497be65fba84913b7d0cb55158f4e7922298923286a7f6156" }, { "index": 2, "output_hash": "fa3f040de013ddbe4a5746c89d32de2cac147845682e7d26119fd686a57e0b65", "output_index": 2549, "value": 2930000, "address": "19M1EraiuAvZp8ZV7QJHH2LVkYm8ECufCJ", "type": "pubkeyhash", "multisig": null, "script_signature": "0x47 0x304402207266d8c69d2c28e4050a90f48209768554e1470999a2259b000fd3c096edc39f02207b7f6a6b7ca7952249a1a1f3064e6a3f573fcd6700084e2fe71ce8f3d3f2be8301 0x21 0x02aa6584518e528be497be65fba84913b7d0cb55158f4e7922298923286a7f6156" }, { /* ... */ } ], "outputs": [ { "index": 0, "value": 70000000, "address": "1JSywyhFSvCC4NGALvKoyX5xng86QaigAN", "type": "pubkeyhash", "multisig": null, "script": "DUP HASH160 0x14 0xbf641337e3ab4eaae788a72bafedb965749882b2 EQUALVERIFY CHECKSIG", "script_hex": "76a914bf641337e3ab4eaae788a72bafedb965749882b288ac", "spent_hash": "71acf863d37d9d18524607e3dd68128b91ddc43dfe32f620ec124ceff3bb3295", "spent_index": 34 }, { "index": 1, "value": 30000, "address": "19M1EraiuAvZp8ZV7QJHH2LVkYm8ECufCJ", "type": "pubkeyhash", "multisig": null, "script": "DUP HASH160 0x14 0x5b8986608535c96923769138ad5be236a091b791 EQUALVERIFY CHECKSIG", "script_hex": "76a9145b8986608535c96923769138ad5be236a091b79188ac", "spent_hash": "400f77fff18e24d1a770c0e1ca85434ca5e4cd0f6e1489e5849256cc71f9ec0a", "spent_index": 2 }, { /* ... */ } ] }

I am finding that if I have "0"(zero) value in form select option, it won't select this option or submit data. If I change this value to any other number to text, it will work. Is there a way to fix this? I have to have an option where I am able to choose to submit "0" value to the database table. <option value="0" <?php if(empty($_POST['special'])) {} else { if($_POST['special'] == 0) { echo 'selected'; } } ?> >None</option> -
Hi everyone, The following code is aimed to show "aaa aaa" as default value for input box in a form: <?php //xxx.php $db = mysqli_connect('localhost', '', '', ''); ?> <!DOCTYPE html> <html> <body> <form method="POST" action="xxx.php"> <input type="text" name="id" class="id_input" value=<?php echo 'aaa aaa';?>> </form> </body> </html>

Php Gurus, I have been doing guess work all this time. But not any more. Just gonna ask. Look at the following code: Concentrate on line 5. It is obvious the "$colors" represent the variable name of the whole array thing (or "column" or "row" in MS Excell terminology). But what does the "$value" represent ? Each array's values (or "cell" value in MS Excell terminology) ? So, the value of the variable $value changes on each loop. Right ? From "Red" to "Orange" at the end. Correct ? Example: 1st loop: $value = Red; 2nd loop: $value = Green; And so on. Correct ? <?php $colors = array("Red", "Green", "Blue", "Yellow", "Orange"); // Loop through colors array foreach($colors as $value){ echo $value . "<br>"; } ?>
